When does an electric short circuit occur?

Answer:

A short circuit occurs when the current in the circuit rises rapidly and the electrical connection draws an excessive amount of current from the supply.

Short circuit can occur when:

  • When too many appliances are connected to a single socket or when high power rating appliances are connected to a light circuit, the resistance of the circuit becomes low as a result the current flowing through the circuit becomes very high
  • If the insulation of the wires used in the circuit is damaged or the appliance used is faulty due to which the live wire and the neutral wire comes in direct contact as a result current in the circuit rises and the short circuit occurs.
