[Elecraft] Fw: K3 Suddenly died
What is most amazing about this thread is that two sides can state the exact same thing, but find fault with and argue with the other.. (???) It's bordering on comical. 73, Charlie k3ICH - Original Message - From: Walter Underwood wun...@wunderwood.org To: Richard Fjeld rpfj...@embarqmail.com Cc: Elecraft Reflector elecraft@mailman.qth.net Sent: Monday, October 07, 2013 12:26 PM Subject: Re: [Elecraft] K3 Suddenly died Of course. My point was for a given current, so 20A at 120V and 20A at 13.8V. --wunder, K6WRU On Oct 7, 2013, at 9:03 AM, Richard Fjeld wrote: I stated the voltage drop across a resistance (the wire conductor) is directly proportional to the amount of current flow (amperage) through it.

If the voltage drop on your power supply wire is 2V for a given current, that is the same regardless of the supply voltage. With a 120V supply, the wire will deliver 118V and with 13.8V it will deliver 11.8V. So the same voltage drop can matter more at lower supply voltages. Note that I'm ignoring the difference between AC and DC and skin effect. wunder K6WRU __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Apparently Ohm's Law is too complicated to argue about on here. Let's go back to discussing whether or not you can read the Heisenberg uncertainty quantity (10-34 joule-seconds) on your voltmeter.

well. If it is a Simpson 260, I'm sure you can You can read ANYTHING with a Simpson...;) Sent from my Verizon Wireless 4G LTE DROID __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Fw: K3 Suddenly died
You can read ANYTHING with a Simpson... Including: 1 -- orientation of the meter. Try it. Zero the scale with the meter vertical and then lay the meter on its back. Different readings. 2 -- the static charge on the meter glass. 3 -- ... I'll just stop at two for now Mark On Mon, Oct 7, 2013 at 2:34 PM, Harlan hsherr...@reagan.com wrote: well.
