In the circuit shown the cells `A` and `B` have negligible resistance. For `V_(A) = 12 V, R_(1) = 500 Omega` and `R = 100 Omega`, the galvanometer `(G)` shows no deflection. The value of `V_(B)` is

A

12V

B

6V

C

4V

D

2V

Text Solution

Verified by Experts

The correct Answer is:
4
`V_(B)=`potential drop across R
`rArr V_(B)=((R)/(R+R_(1)))V_(A)=((100)/(100+500))(12)=2V`
