If a certain resistor obeys Ohm's law,its resistance will change:
A)as the voltage across the resistor changes.
B)as the current through the resistor changes.
C)as the energy given off by the electrons in their collisions changes.
D)none of the above,since resistance is a constant for the given resistor.

Question

Quizplus · Accepted Answer

Ohm's law states that the resistance of a resistor is constant and does not change as the voltage or current changes. Therefore, the answer is D, none of the above.
