Question

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

Answer 1

Answer:

1 unit of energy is equal to 1 kilowatt hour (kWh).

1 unit = 1 kWh

1 kWh = 3.6 x10^{6}106  J

Therefore, 250 units of energy = 250 x 3.6 × 10^{6}106  = 9 x 10^{8}108  J.

Answer 2

Answer: 1 unit=1kWh

So 250 units=250kWh

we know, 1kWh= 3.6X10^6 J

250kWh=250X3.6X10^6J

=9X10^8J
