At the time of short circuit, the current in the circuit:

During a short circuit, the current in the circuit dramatically increases. This is due to the fact that a short circuit creates a path of least resistance for the electrical flow.

Here are the steps that explain this process:

1. Under normal conditions, the current in a circuit follows the path of least resistance, which is the path intended for it - through the various electrical components or appliances connected to the circuit.

2. A short circuit occurs when a "shortcut" is created in the circuit, bypassing the path of higher resistance (the path through the appliances) and instead creating a new path of very low resistance.

3. Because electrical current always follows the path of least resistance, when a short circuit occurs, the current in the circuit will follow this new low-resistance path.

4. This causes a sudden, dramatic increase in the current flowing through the circuit.

5. This sudden increase in current can cause a variety of problems, including overheating, fires, and damage to electrical components. This is why circuits are often protected by fuses or circuit breakers, which are designed to interrupt the circuit if a short circuit occurs.
