Question
In the given figure, of potentiometer V₀ = V_i (R₀/R_i) only when
Options
A. R_L = 0
B. R_L = ?
C. R_L is neither low nor high
D. R_L is low but not zero

Correct Answer

R_L = ?

Explanation

If R_L is not infinite, the voltage ratio of potentiometer depends on the value of R_L. This is called loading effect.
