When three identical bulbs of `60 W, 200 V` rating are connected in series to a `200 V` supply, the power drawn by them will be

A

180 watt

B

10 watt

C

20 watt

D

60 watt

Text Solution

Verified by Experts

The correct Answer is:
C
If rated voltage = supply voltage then in series combination of bulbs
`1/P_(eq)=1/P_1 + 1/P_2 + 1/P_3` + …..
For this equation
`1/P_"eq"=1/60+1/60+1/60=3/60=1/20 rArr P_(eq)`=20 watt
