Answer: (3) Increases heavily
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.
- During this time, the current has a very large magnitude. It occurs when the neutral and live wires come into contact.
- If the insulation on the wires in the circuit is damaged or the appliance is defective, the live and neutral wires come into direct contact, causing current to rise in the circuit and a short circuit to arise.
