A) Attach resistance in series with battery
B) Increase resistance in main circuit
C) Decrease resistance in main circuit
D) Decrease applied emf
Correct Answer: B
Solution :
To shift the balance point on higher length, the potential gradient of the wire is to be decreased. The same can be obtained by decreasing the current of the main circuit, which is possible by increasing the resistance in series of potentiometer wire.You need to login to perform this action.
