Question

In the given figure, of potentiometer V0 = Vi (R0/Ri) only when-A-RL = 0B-RL = &infin;C-RL is neither low nor highD-RL is low but not zero-B-RL = &infin;

APTITUDE CRACK · Accepted Answer

The correct option is  B RL = &infin; If RL is not infinite, the voltage ratio of potentiometer depends on the value of RL. This is called loading effect.
