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.
