MCQ
A potentiometer is an ideal device of measuring potential difference because
  • A
    It uses a sensitive galvanometer
  • It does not disturb the potential difference it measures
  • C
    It is an elaborate arrangement
  • D
    It has a long wire hence heat developed is quickly radiated

Answer

Correct option: B.
It does not disturb the potential difference it measures
b
(b) In balance condition, potentiometer doesn't take the current from secondary circuit.
