Question

which one has more resistance hundred watt bulb or 60 watt bulb both operating at 220 volt​

Answer 1

Answer:

The resistance of 60 watt bulb is greater than the resistance of hundred watt bulb.

Answer 2

Answer:

▶Here's your answer

⏩Let is first look at 100 Watt bulb...

⏩By

$power \: = \frac{ {voltage}^{2} }{resistance}$

⏩So V=220 V, R=? power =100W

$100 = \frac{ {220}^{2} }{resistance} \\ \\ 100r = 48400 \\ \\ r = 484 \: ohm$

⏩Similarly here, R =? V=220 V, P =60 W

$60 = \frac{ {220}^{2} }{r} \\ \\ r = \frac{48400}{60} = 806.6 \: ohm$

⏩Therefore 60 Watt bulb will have better resistance..

Hope it helps ✌
