What are the three basic parts of an electrical circuit?

The three basic parts of an electrical circuit are indeed the source, load, and switch. The source provides the electrical energy necessary for the circuit to function, such as a battery or a power supply. The load represents the component that consumes energy to perform work, like a light bulb or a motor. The switch allows for the control of the flow of electricity in the circuit, enabling it to be turned on or off as needed. This trio is fundamental to understanding how an electrical circuit operates, as they work together to create a complete and functional system.
