Question

There are two bulbs marked as first 60 watt , 220 volt second marked as 100 watt , 220 volt which one of them has higher resistance

Answer 1

P = V² / R

R 1= 48400 / 60
R 1 = 8066.6 ohm

R 2 = 48400 / 100
R2 = 484 ohm

R1 is greater

the bulb with power 60 watt have higher resistance to

Answer 2

hello friend
AS we know that P = V2/ R
ACC.to this whose power is less it's resistance will high
answer is the bulb marked as 60 watt
hope it helps u
