Q1 circuit breakers safer thanfuses? 2 Answers-John Merrill , studied ElectricalEngineering at Northeastern University Answered 1h ago First need tounderstand the concept of Safe Enough. For example on ahigh balcony is a 46 in railing safer than a 42 in railing? While from a highlytechnical point the answer is yes. Does the difference really matter? Not asfar as many Building codes are concerned. Returning tocircuit breakers. The number one advantage is convenience. The operator doesn’thave to run out and purchase the correct sized fuse element to replace everytime there is an overload. From a safety perspective the biggest risk is theoperator installing the wrong (Oversized) value fuse into the fuse holder. To their actualpurpose of protecting the wiring and/or appliance being powered. Both fuses andcircuit breakers are tested and certified to meet the requirements. Are SafeEnough. The reason whyfuses are being eliminated from Building Codes has to do with Operatorsinstalling the wrong fuse, Not with any inherent flaw with fuse design. In factthe fuse offers one significant advantage over a circuit breaker which stilldrives it’s use in certain applications. Circuit breakers bytheir design represent nearly zero resistance to current flow up until the timethe contacts within the device actually move. This delay is typically a fewcycles of the AC Waveform. During that time the actual fault current can riseto over 10 times the value of the breaker. Note in the US we test commonbreakers (15 & 20A) to withstand 10,000A during this interval. A fuse by contrastdoesn’t have this same delay. Their resistance to current flow changes within asmall fraction of a single AC wave. Thus for circuits requiring the veryfastest protection, such as protection of Semiconductors, you will find fuseshave been designed in. Not something the typical person will ever be involvedin/ or seeing. But it is the more complete answer to you question. 2ND ANSWER- Gopala Krishnan , former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966-2004)Answered just now Basically thefunctioning of circuit breaker is different from fuses. A type of wire whichwould fuse double the fuse value is provided in fuses. If a fuse is broken, wemay often replace the fuse. FAULT IS NOT TRACED by many. In circuit breakers,it would again operate and make the circuit break until the fault is traced andset right. Before theinvention of circuit breakers we used fuses every where, but on those daysbefore putting new fuse, checking was done and again fuse was provided. Q2 Why do bus models used by roadtransport departments of Kerala and Tamil Nadu seem to be outdated whencompared with Karnataka? A2 PrafulKodli August 7 Karnataka changedit's overall KSRTC system into 5 different corporations for different part ofstate. Having governing bodies, budget, infrastructure and Man power separatelyyet reporting under state transportation ministry. This segregation allowed Transport industry of Karnatakabloom well. There is an IAS grade officer governingthese 5 bodies . According to environment policy and pollution control policyfor urban areas certain vehicles will have to be taken retired after a set particularperiod in Karnataka. That's why you see other than Urban areas these old busesare sent to secondary regions of the state. I see the longtravels buses (Luxury, AC, Volvo) of TN and Kerala are quite good. Q3 What is the origin story ofvadacurry and why it is so famous in Chennai than other districts of Tamilnadu? A3 SubramaniamDuraisamy Lives in Chennai, Tamil Nadu, India August 29 Thanks for the A2ANiranjan Ji..;) Vadacurry is a dishthat was ‘invented’ to avoid food wastages - especially wastage of vadas andonions - typically by road-side shops in Chennai. Now why do I say‘invented’ in “”?. Because- vadacurry was made out of a necessity to preventwastage of food and not a natural dish native to any culture. To understand thehistory of vadacurry, we need to first understand the history of Chennai city. Chennai - though agreat city today, but it was just a fishing hamlet before the advent ofBritish. And fishing hamlets do not have any grand food culture to boast of.Thus whatever food you see popular in Chennai- be it idly, medhu vada, masaladosa, kothu barotta, vadacurry, pav bhajji - all came here via immigrants fromother parts of the country and world who came to work here for a living. Vadacurry is atypically a dish which was a innovative way to consume the leftover unsoldvadais from the previous day. Street food stalls were typically set up bymigrants and the demographic which used to dine at these street food shops werealso migrants and lower class, and wastage of food actually hurt them bad. I have occasionallyeaten in these street food shops when I used to work late in night-shiftsduring my TCS days. Peak hours is typically from 7PM- 10 PM. If you happen toeat in any road side shop after 10 PM - you can actually observe the hugequantity of vadais [aama vadais and paruppu vadais, to be exact] which would becarried over to the next day usually wrapped up in newspapers like this: These vadais cannotbe stored overnight and consumed next day, because it would get hard due to theonset of bacteria and moisture. Migrant shops do not have the luxury ofrefrigirators for storing vadai baters. Thus there was a pressing need forconsuming these hard, old vadais before its too late. *Enters the idea ofvadacurry* Whenever there areunsold vadais from the previous day, they can be brushed with oil and steamedto remove any bacteria and then air-fried with vegetables like onions to giveextra flavour..;-) This is howvadacurry became popular in Chennai. It was a migrant dish, but prepared by themigrants when they wanted to save on unsold food being wasted. Basicallyconvert it into a thick gravy format and consume it with regular dishes..;-) Set dosa with vadacurry is a very popular dish even in fancy restaurants. Other combinationswhich pair well are idly-vadacurry, chapatti-vadacurry. Q4 A person is already working asAsst.

Q5 How much time is taken for an ROservice and what is the Minimum amount paying to an engineer? A5 GopalaKrishnan, former Assistant General Manager 1996-2004 at Department of Telecom(1966-2004) Answered just now I am living inChennai, India. RO service technician charges Rs 350–00 per visit and cost ofparts charged . AMC is available for Aqua water purifiers@ Rs 2800-00 includingparts cost for 18 months. Q6 Are appendices vestigial? A6 KenSaladin Former professor of histology (microscopicanatomy) Wed Yes, but that doesn’tmean useless.A vestigial organ is one that has, over time, become reduced infunction and usually size, but it can still have functions.The human appendixis a greatly reduced organ compared to that of the other great apes likegorillas and chimpanzees, but it’s still important as a source of GI-regulatinghormones and immune cells. We can live without it, but we can live better withit. Q7 What's the truth behind a driverstopping the Mumbai local train and urinating in front of it? A7 SushangAgnihotri Knows Gujarati August 26 This picture isfrom July 2019. In this, a person is seen urinating standing in front of thetrain. It is shown in thevideo that after urinating, he sits back in the driver's place and startsdriving the train, which proves that it was the train driver. This video was madeby a journalist named Sonu Shinde. What is its truth? The case is similarto what is seen in the video. This motorman while talking to the media toldthat due to the long working time, he did not get an opportunity to lightenhimself and this was distracting his attention. That is why he immediately gotdown at the red signal and peeped so that he would not have trouble running thetrain. I understand thereis no need to make a fuss on Twitter about this, it was a compulsive step. Manypeople are also saying on this that the railways should also provide toiletsfor the driver in the train itself so that it does not happen next time. Q8 Which is more harmful, hightemperature or high humidity? A8 RohanBhairat, Student (2021-present)Answered 51m ago Hot, humid summerdays can feel unbearable sometimes. Humidity, or the amount of moisture in theair, can make the temperature feel warmer, as our sweat is slower to evaporate.Not only is the muggy air uncomfortable, but it can cause our bodies tooverheat, exhaust easily, and poses a potential danger to our health. Q9 Why were many kings denied entryto Yudhisthira's palace during Rajasuya Yagna? A9 BhanuKiran Exploring ancient texts of Sanatana Dharma Wed Yes it is true thatmany famous kings were denied entry into the palace of Yudhisthira. Thegatekeepers collected the gifts and sent off many kings without allowing themto enter inside. ‘“Maharatha King Bhagadatta, the braveruler of Pragjyotisha and the strong ruler of the mlechhas, came with yavanas.He brought a tribute of thoroughbred horses, as swift as the wind, but wasbarred and stood at the gate. After presenting a receptacle that was like ironand swords with handles of ivory, Bhagadatta of Pragjyotisha left. I saw thatmany people from different directions were refused admission at the gate,though they brought rich tributes of gold and silver—with two eyes, three eyes,one eye on the forehead, those who wore headdresses, those who had no fixedabode, Bahukas, cannibals and those with only one foot. There were peoplefrom all around Aryavarta and also from China. The gifts were innumerous andYudhisthira's richness is compared to that of gods. “They also gave himrich tributes of the best quality of gold. There were Chinas, Hunas,Shakas,Oudras, those who live inside mountains, Varshneyas, Harahunas, darkones and those who live in the Himalayas. I do not remember the order of thosewho were barred entry at the gate. Source: Mahabharatatranslated by Bibek Debroy Dyuta Parva 272(47) There was no placeto keep the continuous incoming gifts. Indraprastha was flooded with gifts andit was difficult to decide whom to allow inside and whom to deny. The strongresidents of the mountains brought as tribute dark and coloured tails of yaksand others that were as white as moonbeams, a lot of sweet honey from theflowers of the Himalayas, garlands and water from the northern Kuru region andimmensely powerful herbs from northern Kailasa. They bowed and stood at thegate of King Ajatashatru, but were denied entry. O lord of the earth! Therewere kings from the other side of the Himalayas, from the mountains where thesun rises, from the banks of Varishena and Lohitya, from the banks of the oceanand kiratas who live on roots and fruit and wear skins. They brought largemasses of sandal and aloe wood, kaliya, skins, jewels, gold, fragrances, tenthousand kirata slave girls, beautiful animals and birds from distant regionsand copious quantities of radiant gold from the mountains. But despite all thistribute, they were refused entry and waited at the gate. ThereforeYudhisthira decided to allow only those people who bring in large tributes.Below is the reference which says people who brought large tributes wereallowed to enter inside Indraprastha. On the instructionsof the king, the gatekeepers told them, ‘If you bring large and great tribute,only then will you be admitted.’ So they each gave one thousand elephants, withtusks like the shafts of ploughs, caparisoned in gold and covered in cushionswith the colour of lotuses. They were as large as mountains, always in rut andcame from the shores of Kamyaka Lake. They were covered in armour, patient andtrained well. They then entered the gate.

A10 GopalaKrishnan , former Retired Assistant General Manager 1996-2004 at Department ofTelecom (1966-2004) Answered just now Water is a liquid whichwould wet the surface of the container. So a small quantity is lost in wetting.While heating bubbles comes and burst. This creates some more loss of water.Unless boiled water will not be lost as steam Q11 Should I apply oil to the whole bodybefore a bath? A11 GopalaKrishnan, former Assistant General Manager 1996-2004 at Department of Telecom(1966-2004)Answered Thu Forchildren/infants oil bath is given daily. Adults oil bath is taken once/twice aweek among people in Tamil nadu. As age advance taking oil bath once month willsmoothen the skin Q12 How do you start a day if rainshould break your routine?
