The tungsten filaments of two electric bulbs are of the same length. If one of them gives power and the other power. Then
View answer and explanation
Correct option: C
bulb has thicker filament
Option C ( bulb has thicker filament) is correct because for a given voltage, higher power implies lower resistance, which means a thicker filament.
