Flow of Electrons - JSS3 Basic science Lesson Note

Electrons flow through a circuit from the negative terminal of the voltage source (like a battery) to the positive terminal. This flow is driven by an electric field created by the voltage source.

When a circuit is completed, meaning it forms a continuous path, electrons move through conductors like wires, components (such as resistors, capacitors, and light bulbs), and back to the voltage source. This flow of electrons is what creates electric current, which is measured in amperes (A).
