Hey, I looked all over for this information, but all I could find were applications of the formula. None of the sources I found actually described what a "temperature coeffecient" was or how it is derived.

Equation that I'm talking about:

R(sub t) = R(sub 0)(1 +

That's "R sub t is equal to R sub zero multiplied by the quantity one plus aT

T is temperature, R sub zero is initial resistance, and R sub t is final resistance.

Where "

I'm basically trying to understand why there would be a coeffecient for an environmental dynamic variable like temperature.

Thanks a ton,

hinges

**a**" is the temperature coeffecient (It's the formula for determining resistance of thermisters, or any resistor whose resistance changes as a function of temperature)I'm basically trying to understand why there would be a coeffecient for an environmental dynamic variable like temperature.
