Both uses same amount of energy.

250watt-hour.

The product of the total power consumed by equipment and the total time in which the equipment used is called energy consumption of that equipment.

Energy=power#xx#time

E=P.t

For a TV set:

#E=250Wxx1hr#

#E=250#watt-hour#" " color(blue)((1))#

For a toaster:

#E=1500Wxx10#minutes

#E=1500Wxx10/60hr#[since 1hr=60minutes]

#E=250#watt-hour#" " color(blue)((2))#

From#" " color(blue)((1))#&# color(blue)((2))#;

We are able to know that both requires same amount of energy
for given durations.
