1689 - How does a current carry energy in a circuit?

Imagine water flowing through a hose. The water molecules are like tiny particles called electrons in a circuit. When water flows through the hose, it carries energy from the beginning (where the water pump is) to the end (where the water sprays out).

In a circuit, electricity works in a similar way. Electrons (those tiny particles) flow through a wire, carrying energy from the beginning (like a battery) to the end (like a light bulb). As the electrons move, they transfer their energy to the devices connected in the circuit, making them work. This flow of electrons is what we call an electric current.
