A car battery of emf 12V and internal resistance `0.05 omega` receives a current of 60 A from an external source, then the terminal potential difference of the battery is

A

12 V

B

9 V

C

15 V

D

20 V

Text Solution

Verified by Experts

The correct Answer is:
C
`V = E + IR`
`= 12 + 60 xx 5 xx 10^(-2)`
`= 12 + 3`
` = 15 V`
