Question 17:
When does an electric short circuit occur?
Answer:
If the resistance of an electric circuit becomes very low, then the current flowing
through the circuit becomes very high. This is caused by connecting too many
appliances to a single socket or connecting high power rating appliances to the
light circuits. This results in a short circuit.
When the insulation of live and neutral wires undergoes wear and tear and then
touches each other, the current flowing in the circuit increases abruptly. Hence,
a short circuit occurs.
