In a message dated 01-01-18 18:09:55 EST, you write:
<< I don't think thats true with a true resistor although thermal runaway does
happen with some types of semiconductors. >>
I'm not talking about resistors........just plain electrical conductor.
Resistors are made to resist current to flow, when you resist current you'll
have voltage drop across a resistor....this depends on what connection u
have......
-voltage source with resistor connected as parallel will give you the same
voltage readings as the voltage source...but different current value
-voltage source with resistor connected as serial will give u different
voltage drop readings compared to parallel connection....but maintains
CURRENT value.
About your thermal runaway on semiconductors it is a conduction when heat is
causing more electrons to propagate across semiconductor's junction which in
turn generates more heat....which leads to burning the whole chip itself. A
semiconductor is vulnerable to thermal runaway if is cause by:
-Voltage and current requirements are not within spec range or exceeds it
limits
-External heat
-No proper ventilation
-spikes.......unregulated power supplies
<<Ever feel how warm your plug wires get from passing 15k volts and very
little current? Not very warm at all...>>
-engineers designed it to withstand that kind of value....problem is external
heat coming from engine it affects electrical performance....i think even if
heat is present...the wires still maintain the same 15kV output value to the
plugs
<<Yeah, you will see a difference but the voltage drop is not from the heat.
Think about it, where does the heat from your heater come from, the heater
core right? How does passing air through a small radiator
drop the voltage at the battery. The voltage drop is there because the
blower motor is sucking more current.>>
next time try not to turn on the FANs......just the heater @ max.....
<<This is the correct
order with the specific resistance in ohms of each type of wire being 1 foot
long: Silver (9.9), Copper (10.4), Gold (14.7).

You're are correct!.......I'm wrong....
<<Ahhh NOPE! Its silver, copper THEN gold. Gold is most commonly used in
connectors since it doesn't oxidize and provides a good clean connection,
not because it is a superior conductor with with almost no resistance. Not
to mention it is soft and maleable letting it conform to the mating surface
at the microscopic level for an even better connection.

You are correct too!.
<<I'm not trying to rip your head off or humiliate anyone here but please get
the facts straight.
Ken>>
Well if I'm wrong just correct me and I'll be glad to hear your intelligent
corrections.
I know you're better than me...
