Question

Find the power consumed in the problem given below

Answer 1

given,

power=1000W

time=90 min (90*60=5400 sec)

power=energy/time

1000=E/5400

1000*5400=E

5400000=E

therefore energy consumed in one day=5400000 joules.

therefore in 30 days energy consumed ,

30*5400000=162000000.

∴energy consumed in 30 days=1.6*10^8.

I hope that this will help u..........................
