A battery of emf 10 V and internal resistance 3 ohm is connected to a resistor. The current in the circuit is 0.5 A. The terminal voltage of the battery when the circuit is closed is

A

10 V

B

0 V

C

1.5 V

D

8.5 V

Text Solution

Verified by Experts

The correct Answer is:
D

Terminal voltage `V=E-Ir`
`V=10-0.5xx3=10-1.5=8.5 V`
