According to Ohm's law, assuming that the voltage is held constant, what will happen to the re-sistance if the current is doubled?
a. It will remain the same. c. It will quadruple.
b. It will be doubled. d. It will be halved.
ANS: D
Given the fact that when resistance is constant, there is a direct relationship between voltage and current; when voltage is constant, there is an indirect or inverse relationship between current and resistance. Therefore, if current is increased, resistance would have to decrease proportionately.
