Explain the meaning of overloading of an electrical circuit. List two possible causes due to which overloading may occur in household circuits. Write one preventive measure that should be taken to avoid overloading of domestic circuits.
Solution
Overloading : Overloading of an electrical circuit happens when an excessive amount of electric current flows through the wires.
Two causes :
(i) Contact between live and neutral wire/ short circuiting
(ii) Connecting too many appliances to a single socket.
(iii) Accidental hike in supply voltage (Any two points) (Any other)
Preventive measure :
(i) To use wires of proper insulation/proper rating
(ii) Not connecting too many appliances to a single socket.
(iii) fuse wires (Any one)
