Answer:

heater

Explanation:

because it take 600 W in 20 mins and 900 w in 30 mins but tv set takes only 500 w in 30 mins so heater will spend more electrical energy

Answer:

The answer will be the heater consuming 600 watts power in 20 minute.

Explanation:

Here the explanation goes.

We have given;

A TV set with :

Power (consuming) = 500 W;

Time taken = 30 minutes;

Time in seconds = 30 * 60 = 1800 seconds;

A heater with :

Power (consuming) = 600 W;

Time taken = 20 minutes;

Time in seconds = 20 * 30 = 600W;

Also, we know that there's a relation between power, energy and time and that is given by;

Power = Energy / Time;

Energy = Power * time;

Now, in the case of the TV set,

Energy consumed = 500 W / 1800 sec

= 5 / 18 (W/sec)

= 5/18 joules

and, in the case of heater,

Energy consumed = 600 W / 600 seconds

= 1 joules

Here we can, obvisiouly, see that energy consumed by heater is greater than that of tv set.

Hence, the heater will spend more electrical energy in the two of them.

That's all.
