Question

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

Answer 1

Answer:

power consumed by one device=250 watt

power consumed by four devices=250×5

                                                     = 1250 watt

time taken=10 hours

                                         energy=power × time

energy consumed=1250 × 10

                              =12500 J

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

Answer 2

$\huge{ \red{ \fbox{↪ answer :  }}}$

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.
