Question

2. An electric bulb is rated 220 V and 100 W. When it is operated on 110
power consumed will be -
(a) 100 W
(b) 75 W
(c) 50 W
(d) 25 W
​

Answer 1

Explanation:

power is directly proportional to voltage

100 = k*220

where k is constant

k = 100/220 = 5/11

when v=110 volt

power = 110*(5/11) = 50 watts

option c is correct
