Question

The power of an electric heaters is 1500 watt. How much energy it consumes in 10 hours?

Answer 1

Formula :

Power = Work / time

Given :

Power = 1500 W

Time = 10 hr

Work

Energy is the capacity of doing work

By the formula :

1500 W = work / 10 hr

= > work = 1500 W × 10 hr

= > work = 15000 Whr

15000 Whr is the energy consumed .

1 Whr = 3600 J

15000 W hr = 15000 × 3600 J

                    = 54000000 J

                    = 5.4 × 10⁷ J

ANSWER :

5.4 × 10⁷ J is the energy consumed .

Answer 2

54000000 joules is the ans i got
