Theoretical Negative Power and Resistors
We have referred to resistors dissipating heat, i.e., we have assumed that P = I∆V is always greater than zero. Could I∆V come out to be negative for a resistor? If so, could one make a refrigerator by hooking up a resistor in such a way that it absorbed heat instead of dissipating it?
Homework Answers
No, power can't be negative. In our calculations , sometimes V is negative because of our reference of 0 potential.
Power dissipated from a resistor can never be negative. As we only take magnitudes of V and I to calculate power dissipated from a resistor.

1)If one measures the current in series resistors, is the current measured before the resistors different than what measured between the two resistors? a) no difference, current is the same b) the difference depends on the direction of the current c)the current after the first resistor will decrease d) yes, they are different If one measures the current in parallel resistors, are the currents in parallel resistors always the same? a) no, only currents in series resistors are the same...

True or False: 1. Resistors connected in series always have equivalent resistance greater than any individual resistor. 2. Resistors connected in parallel have equivalent resistance greater than any individual resistor. 3. Most materials have increased resistance as they heat up. 4. A battery's primary function is to provide charge and power to a circuit. 5. The voltage difference between two points in the same (ideal) wire is ALWAYS 0.
