Find the power supplied by `20 V` cell in the figure shown.

A

`- 10 W`

B

`20 W`

C

`- 20 W`

D

`10 W`

Text Solution

Verified by Experts

The correct Answer is:
C
(c )Taking point 'A' as reference potential and its potential to be '0' : `I = 20 A`
Power supplied by `20 V` cell `= - 20 xx 1 = - 20 W`
