Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Increase heavily
A short circuit is a direct contact between the live and the neutral wires, which leaves almost no resistance in the path of the current.
By Ohm’s law I = V/R, and as R falls almost to zero the current rises enormously. It is this sudden surge that heats the wires, blows the fuse or trips the circuit breaker.
