Question

Find the energy consumed in 10 hours by 5 devices of power 250 W each.​

Answer 1

power consumed by one device=250 watt power consumed by four devices=250x5

= 1250 watt

energy=power x time

energy consumed=1250 x 10

=12500 J

one power :when one joule energy is consumed per hour thin this is called one power or one watt.

Answer 2

Hey legend... here's your answer...

power consumed by one device=250watt

power consumed by one device=250wattpower consumed by five devices=250×5 =1250 watt

power consumed by one device=250wattpower consumed by five devices=250×5 =1250 watttime taken =10 hours

power consumed by one device=250wattpower consumed by five devices=250×5 =1250 watttime taken =10 hours energy=power×time

power consumed by one device=250wattpower consumed by five devices=250×5 =1250 watttime taken =10 hours energy=power×timeenergy consumed =1250×10

power consumed by one device=250wattpower consumed by five devices=250×5 =1250 watttime taken =10 hours energy=power×timeenergy consumed =1250×10 =12500J
