In a potentiometer of 5 wires, the balance point is obtained on the 3rd wire. To shift the balance point to the 4th wire,

A

current of the main circuit is to be decreased.

B

current of the main circuit is to be increased.

C

the shifting is not possible

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
A
To shift the balance point of a potentiometer to a higher length, the potential gradient of the wire is to be decreased. This can also be achieved by decreasing the current of the main circuit. So, this is a true statement.
