  • Question

  • In the given figure, of potentiometer V0 = Vi (R0/Ri) only when
    In the given figure, of potentiometer V0 = Vi (R0/Ri) only when RL = 0 RL = ? RL is neither low nor


  • Options
  • A. RL = 0
  • B. RL = ?
  • C. RL is neither low nor high
  • D. RL is low but not zero

  • Correct Answer
  • RL = ? 

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