Current Electricity - Result Question 108
113. Potentiometer measures potential more accurately because
[2000]
(a) it measures potential in the open circuit
(b) it uses sensitive galvanometer for null deflection
(c) it uses high resistance potentiometer wire
(d) it measures potential in the closed circuit
Show Answer
Answer:
Correct Answer: 113. (a)
Solution:
- (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.
