Energy consumed by the TVset = 250*3600 =9*105J ∴ Energy consumed by a toaster = 1200 × 600 = 7.2× 105J ∴ the energy consumed by a 250 W TV set in 1 h is more than the energyconsumed by a toaster of power 1200 W in 10 minutes.

  • Energy used by 250W Tv set in 1 hour :-

⸻➤ W = 250 × 1 h = 250 Wh.

  • Energy used by 1200 W toaster in 10 min = 1/6 h.

⸻➤ w = 1200 × ( 1/6 ) h = 200 Wh.

  • Thus , a 250 W Tv set uses more power in 1 h than a 250 W toaster in 10 minutes.

Hope it helps you
