Current Electricity

  1. Potentiometer measures potential more accurately because​​
    1. ​it measures potential in the open circuit
    2. ​it uses sensitive galvanometer for null deflection ​
    3. it uses high resistance potentiometer wire
    4. ​it measures potential in the closed circuit
Correct Option: A

Potentiometer measures potential current more accurately because it measure potential in open circuit and hence error in potential due to internal resistance is removed.
