In a potentiometer experiment, the balancing length is found to be 1.8 m for a cell of e.m.f. 1.5 V. What is the balancing length for a cell of e.m.f. 1 V ?

A

1 m

B

1.5 m

C

1.2 m

D

2 m

Text Solution

Verified by Experts

The correct Answer is:
C
`(E_(1))/(E_(2))=(l_(1))/(l_(2)) therefore (1.5)/(1)=(1.8)/(l_(2)) therefore l_(2)=1.2 m`
