Solution

The correct option is C If a voltmeter is connected across the 6 V battery it will read 7 V

Total resistance = 4 + 1 + 0.5 + 0.5 = 6 ohm
Net voltage in the circuit is 6 V
Current l=66=1 A in the anticlockwise direction
VPR=1× 4=4 V
Since R is connected to earth VR=0 hence Vp=4 V
VSQ=0.5× 1 =0.5 V
S is at a higher potential than Q
VQ=0.5 V
Current is being forced into the 6 V battery in the opposite direction.Hence V6 =E+lr=6+1 X
1 = 7 V
