Answer 2

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.
