HEY MATE..!!

here is your answer ⤵⤵⤵⤵⤵⤵

option D : 25W

explanation:

P = V^2 / R

100=220 × 220

R

R= 220 × 220

100

R = 22 × 22

when 110v is supplied

P = 110 × 110

22 × 22

P = 5 × 5

= 25W

hope this ans helps you...

Answer:

Explanation:

Power P = V²/R

Hence

R = V²/P = (220)²/100 = 484 ohm

Now Again using P = V²/R for 110 volts we get

P = 110*110/484

= 25 Watts
