In potentiometer experiment, null point ...

In potentiometer experiment, null point isobtained at a particular point for a cell on potentiometer wire x cm long. If the lengthof the potentiometer wire is increasedwithout changing the cell, the balancing length will (Driving source is not changed)

A

increase

B

decrease

C

not change

D

becomes zero

Text Solution

Verified by Experts

The correct Answer is:
A

If the length of the potentiometer wire is increased, the potential gradient is decreased and the balancing length is increased.
