1. AN ELECTRIC CIRCUIT

An electric circuit is a pathway for the flow of electrons. It consists of different parts. Electric current is a continuous flow of electrons through a circuit.

1.1. Parts of an electric circuit

Electric circuits consists of various parts:

- Generators provide the energy that electrons need in order to move.

- Loads are devices that transform electrical energy into other types of energy that we can use.

1.2. Diagrams and symbols

We use a system of conventional symbols to simplify the visual representation of electric and electronics circuits, making them easier to understand.
