An electric circuit is a pathway for the flow of electrons. If consits of the following parts, which are connected by wires: A generator that provides energy, elements that provide control and protection; loads that receive and use energy.
Electric current is a continous flow of electrons through a circuit.
PARTS OF AN ELECTRIC CIRCUIT
- Generators provide the energy that electrons need ir order to move.
- Loads are devices that transform electrical energy into other types of energy that we can use.
- Switching devices are used to direct and interrupt the flow of electric current.
DIAGRAMS AND SYMBOLS
We use a system of conventional symbols to simplify the visual representation of electric and electronic circuits, making them easier to understand.
The following table list the most common symbols:
