Question

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

Answer 1

Energy consumed by certain households in a month $E=250$ units $=250$ $kWh$

$\therefore E=250\times 3.6\times {10}^6$ $J$ $(\because 1kWh=3.6\times {10}^{6}J)$

$⟹E=9\times {10}^8$ Joules
