What does the load do in an electrical circuit?

In an electrical circuit, the load is a component that consumes electrical energy. This consumption is usually in the form of converting electrical energy into other forms of energy, such as light, heat, or mechanical work. For instance, when a light bulb is connected in a circuit, it acts as a load by taking in electrical energy and converting it into light and heat energy.

The load is essential for the operation of the circuit because it is the part that uses the energy supplied by the source, such as a battery or generator. When the electrical current flows through the load, it results in the performance of a useful task, making the load a critical aspect of any functional electrical system.
