$\bold\green{Your\:Answer:-}$

Energy consumed by an electrical appliance is given by

H = Pt

For the TV set:

Power W = 250 W

time t = 1 hour = 3600 seconds

So, energy consumed

H = 250 × 3600 = 900000 J

______________________________◾◾◾

For the toaster:

Power W = 1200 W

time t = 10 minutes = 600 seconds

So, energy consumed H = 1200 × 600 = 720000 J

Hence, TV set uses more energy than toaster.

I hope, this will help you___❤❤
