Three electric bubls of 200W, 200 W and ...

Three electric bubls of 200W, 200 W and 400W are shown in figure. The resultant power of the combination is

A

800W

B

400W

C

200W

D

600W

Text Solution

Verified by Experts

The correct Answer is:
C
`1/P = (1)/((200+200)) + 1/400 implies P = 200W`.
