In an electrical circuit, the component supplied by the source voltage is known as?

In an electrical circuit, the component supplied by the source voltage is referred to as the load. The load represents the part of the circuit that consumes electrical power to perform a specific function, such as lighting a bulb, powering a motor, or running an appliance. When a source voltage is applied, it drives current through the circuit, and this current is ultimately utilized by the load for its operation.

In contrast, components like the relay, switch, and conductor serve different roles in the circuit. The relay is a device used for controlling a larger current by using a smaller current; the switch allows for the opening or closing of a circuit to enable or disable the flow of electricity; and the conductor serves as the pathway for electrical current to travel through the circuit. These components are essential for the functionality of a circuit but do not represent the component that consumes the power provided by the source voltage.
