Two electric bulbs one of 200 volt, 40 watt and the other 200 volt, 100 watt are connected in a house wiring circuit.
Correct answer: C. The resistance of the filament in 40 watt bulb is more than the resistance in 100 watt bulb
- A. They have equaI currents through them
- B. The resistance of the filaments in both the bulbs is same through them
- C. The resistance of the filament in 40 watt bulb is more than the resistance in 100 watt bulb
- D. The resistance of the filament in 100 watt bulb is more than the resistance in 40 watt bulb
Explanation
As bulbs are in parallel, they will have same volatge. So, P is inversely proportional to R. Hence, 40 watt bulb will have more resistance.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
