Question

Two bulbs have ratings 100 W, 220 V and 60 W, 220 V respectively. Which one has a greater resistance?

Answer 1

P= V2/ R

So...

60W 220V has greater resistance

Answer 2

$\huge\underline{Hello}$

Power=V^2/R

R=V^2/P

R1=220×220/100

=484 ohm

R2=220×220/60

=806.7

Thus,second bulb has higher resistance .
