In section PQ of a circuit P is at higher potential than Q by 40 V. The potential difference in volt across the battery A is:

A

6V

B

4V

C

2V

D

8V

Text Solution

Verified by Experts

`V_(PQ)=40 volts`
`implies 12-6+(5+8+2+2)i=40`
`implies 17i=34 implies i=2A`
`implies Pd` across battery A is 6-2i=2V
