Which uses more energy a 250 watt TV set in 1 hour or a 1200 watt toaster in 10 minutes?
For TV
Power (P) = 250 W
Time (t) = 1 hr. = 3600 sec
For toaster
Power (P) = 1200 W
Time (t) = 10 min = 600 sec
Now,
Energy = Power × Time
Substitute the known values in above formula for TV
=> 250 × 3600
=> 900000
=> 9 × 10⁵ J
Similarly, for toaster
=> 1200 × 600
=> 720000
=> 7.2 × 10⁵ J
•°• Energy consumed by 250W of TV set in 1 hr. is more than that of the toaster in 10 min
