Answer 1

Given:

An AC with the power consumption of 3000 Watts runs 8 hours a day.

To find:

Units consumed by AC ?

Calculation:

The units of electricity utilised refer to the total energy expended by the electrical instrument in terms of kWhr (Kilo-watt Hour).

$\rm \: energy = power \times time$

$\rm \implies\: energy = 3000 \times 8$

$\rm \implies\: energy = 24000 \: watt \: hr$

$\rm \implies\: energy = 24 \: kilowatt \: hr$

$\rm \implies\: energy = 24 \:units$

So, 24 units of energy has been used.
