Question 64

This question is about the potential difference (p.d.) across, and the current in, a variable resistor.

The resistance of the variable resistor is decreased.

Which statement is correct?

A

The current can remain constant if the p.d. is increased.

B

The current can remain constant if the p.d. is decreased.

C

The p.d. can remain constant if the current is decreased.

D

The p.d. can remain constant if the current is kept constant.
