In the circuit shown the cells A and B have negligible resistances. For VA = 12 V, R1 = 500 and R = 100 the galvanometer (G) shows no deflection. The value of VB is:
4 V
2 V
12 V
6 V
As we discussed in
Option 1)
4 V
This option is incorrect.
Option 2)
2 V
This option is correct.
Option 3)
12 V
This option is incorrect.
Option 4)
6 V
This option is incorrect.
