Homework Help: Resistors and heat?

  1. Aug 6, 2008 #1
    I'm doing coursework and i know it's dumb but i just cant remember how heat is supposed to affect resistors *heh* If someone could give me a quick explanation, it's not for the main part of the coursework, it's just a factor i have to controll in another experiment, but i can't remember why i have to controll it! D:

    thanks, one more question, why would that affect the voltage in a circuit with a resistor?

    Think about Ohms Law.
