(i) State and define the household unit of electricity.

(ii) What is the voltage of the electricity that is generally supplied to a house?

(iii) What is consumed while using different electrical appliances, for which electricity bills are paid ?

$\large \blue \bigstar \: \color{purple}\pmb{\sf{Solution :}}$

(i) The household unit of electricity is kilowatt-hour (kWh). One kilowatt-hour (kWh) is the electrical energy consumed by an electrical appliance of power 1 kW when it is used for one hour. Also, 1 unit = 1kWh

(ii) The voltage of the electricity that is generally supplied to a house is 220 volt.

(iii) Electrical energy is consumed by various electrical appliances. This consumed electric energy is measured in terms of kWh (kilo watt hour) for which electricity bills are paid.
