Question

A certain house hold consumed 250 units of energy during a month. How much is this in joules????

Answer 1

unit means kilowatt hour (kWh)
250 unit = 250kwh
=250×1000×60×60 J
=900,000,000 J

as power(Watt) = energy(juole)/time(second)

energy (juole)=Watt × second

Answer 2

___________________________

We know that

1 unit = 3,600,000 J

So,

250 units

= 250 × 3,600,000 J

= 900,000,000 J

= 9 × 10^8 J

Hence, the energy consumed = 9 × 10^8 J
