What are the two main components of an electrical circuit?

In an electrical circuit, the two main components are the power source and the load. The power source provides the necessary voltage and current to the circuit, which can be a battery, generator, or any other type of electrical supply. The load, on the other hand, is the component that consumes electrical energy to perform work, such as a light bulb, motor, or heater.

This relationship is crucial because the power source initiates the flow of electricity through the circuit, allowing the load to function. Understanding the role of these two components is fundamental in circuit design and analysis, as they form the backbone of any electrical system. When these components are combined properly, they can create a functional circuit that delivers power to devices.
