Which of the following is NOT a component of a basic electrical circuit?

A basic electrical circuit is made up of essential components that enable the flow of electric current. The three primary components are a voltage source, a load, and conductors.

The voltage source, which can be a battery or generator, provides the electrical energy needed to push the electric current through the circuit. The load is the component that consumes the electrical energy, such as a light bulb, motor, or any other device that uses electricity. Conductors are the pathways, such as wires, that allow the flow of electric current from the voltage source to the load.

The switchboard, while it may be an important part of larger electrical systems, is not considered a fundamental component of a basic electrical circuit. Instead, switchboards are used to manage and distribute electrical power in more complex setups, typically involving multiple circuits. Therefore, it does not fit into the category of the basic components needed for the simplest electrical circuit, making it the correct choice for the question.
