At the time of short circuit, the current in the circuit
$(a)$. reduces substantially
$(b)$. does not change
$(c)$. increases heavily
$(d)$. vary continuously

Correct answer: $(c)$. increases heavily

Short circuit:

A short circuit is said to be an electrical circuit that allows current to pass through often when offered resistance is very low.


Example of a short circuit:

A very common example of short circuit occurrence can be seen when the positive and negative terminals of a battery are connected to a thin wire$(with\ a\ very\ low\ resistance)$. Due to very low resistance in the connection, a high current is passed that allows the cell to deliver a large amount of energy in a short period of time.



Conclusion:

Too low resistance in a connection is the main cause of a short circuit and with this low resistance, the current in the circuit increases very much.

Hence, during a short circuit, the current in the circuit increases very high.

Therefore, option $(c)$ is correct.
