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

A.VERIFIED ANSWERfact-checked by tutors

Solution:

1 unit of energy = 1kWh

Given

Energy (E) = 250 units

1 unit = 1 kWh

1 kWh = 3.6 x 106 J

Therefore, 250 units of energy = 250 × 3.6 × 106

= 9 × 108 J.
