Question #c71ac

Answer 1

Both uses same amount of energy.

250watt-hour.

Explanation:

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.
