Question

At the time of short circuit, the electric current in the circuit becomes

• A. very low
• B. does not change
• C. very high
• D. varies continuously

Hint:

In a short circuit, the resistance drops significantly, leading to a massive increase in current. This can cause overheating and damage to the circuit components.

Answer 1

The Correct Option is C

Step 1: What is a short circuit?
A short circuit occurs when the current flows along an unintended path, usually one with very low resistance, such as when the live wire directly touches the neutral wire or the ground.

Step 2: Behavior of the current in a short circuit
In a normal circuit, the current is determined by the resistance of the components. However, during a short circuit, the resistance of the path is very low (ideally zero), so according to Ohm's Law (\( I = \frac{V}{R} \)), the current becomes extremely high as the resistance \(R\) approaches zero.

Step 3: Conclusion
Thus, the current in the circuit during a short circuit becomes very high. The correct answer is option (C).
