Question

which consume more energy a heater of 500W operated for 10 sec or a tv of 100W operated for 30 sec​

Answer 1

Answer:

a heater of 500w run for 10 sec consumes more energy

Answer 2

Answer:

Step-by-step explanation:

We know that energy consumed = Power * time/1000

Calculating the energy consumed for heater

Given that power = 500W

and time = 10 sec

Therefore, energy consumed = 500 * 10/1000

                                                  = 5 J

Calculating the energy consumed for TV

Given that power = 100W

and time = 30 sec

Therefore, energy consumed = 100 * 30/1000

                                                  = 3 J

as 5J > 3J

=> The energy consumption of  Heater > energy consumption of TV

Therefore, the heater consumes more energy.
