Class 10th Physics: Difference Between Short-circuit and Overloading

BY Team Aakash Byju's

Short circuits occur when there is a fault between the line to earth.

A short circuit usually occurs when the neutral and direct wires touch each other.

 A short circuit can be prevented by equipment like a fuse, circuit breaker, etc.

During a short circuit, the resistance of the current path becomes low due to which heavy current flow through the circuit.

A short circuit means the voltage at the fault points reduce to zero, and the large current starts to flow through a circuit.

The voltage at the short circuit decreases to zero.

In overload, the condition of the load greater than the suitable value is applied to the system. In overload, voltage reduces but not be zero.

OVERLOAD

The current in overload condition is high but considerably low to short circuit.

Overload occurs when equipment draws excessive current from the supply.

Overload occurs when the number of device joints in a single socket is more.

The magnitude of the current is high but appreciably low compared to the short circuit current.
