answered 27 Mar 2026A 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.
