Final answer:
An overload is used to protect a load from overcurrent in an electrical circuit.
Step-by-step explanation:
The purpose of an overload is to protect a load from overcurrent. It is a safety measure implemented in electrical systems to prevent damage to equipment and ensure the safe operation of the circuit. When an overload occurs, it triggers protective devices such as circuit breakers or fuses to interrupt the flow of electric current and prevent excessive current from flowing through the circuit.
