Two bulbs of 100 W and 200 W working at ...

Two bulbs of 100 W and 200 W working at 220 volt are joined in series with 220 volt supply. Total power consumed will be approximately.

A

65 watt

B

33 watt

C

300 watt

D

100 watt

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(eff) = (P_(1)P_(2))/(P_(1) + P_(2)) = (100 + 200)/300 = 200/3`
`= 66.67W = 65` watt
