What is short circuiting ? State its possible causes. What is likely to happen if a domestic circuit gets short circuited ? Give reason for the justification of your answer.
Marking-scheme solution
Short circuiting occurs when the live wire and neutral wire of a domestic electric circuit come in direct contact with each other.
Damaged insulation of the live wire and neutral wire, Fault in the electrical appliance/ overloading (Any $\displaystyle 2$)
Due to abrupt increase in the current, the fuse wire will melt and break the circuit.
