Question

At the time of short circuit, the current in the circuit ______.

Options

• reduces substantially

• does not change

• increases heavily

• vary continuously

Answer 1

At the time of short circuit, the current in the circuit increases heavily.

Explanation:

During a short circuit, resistance reduces to almost zero. By Ohm's Law,

V = IR

Since V remains the same and R is reduced significantly, current suddenly increases.
