UPSC CAPF – 2022
According to Ohm’s Law (V = IR), the current (I) in a circuit is directly proportional to the voltage (V) across it and inversely proportional to its resistance (R).
During a short circuit, the resistance (R) in the path becomes very low, ideally approaching zero. If the voltage (V) of the source remains relatively constant, the current (I = V/R) will increase dramatically or sharply.
This sudden surge in current can generate excessive heat, potentially causing damage to the circuit, components, or leading to fires.
