Two electric bulbs, one of `200V, 40W`, and the othere `220V`, `100W` are connected in a house wiring circuit

A

they have equal currents through them

B

the resistance of the filaments in both the bulbs is same

C

The resistance of the filament in `40 watt` bulb is more than the resistance in `100watt` bulb

D

The resistance of the filament in `100 watt` bulb is more than the resistance in `400watt` bulb

Text Solution

Verified by Experts

The correct Answer is:
C

`R_(1) = ((200)^(2))/(40), R_(2) = ((200)^(2))/(100)`
`R_(1) gt R_(2)`.
