The schematic diagram, in which different components of the circuit are represented by the symbols conveniently used, is called a circuit diagram. What do you mean by the term components?
It is difficult to draw the actual parts of the circuit which are in real life so, there is a way to draw the circuit with some suitable symbols. Electric components or simply components of the circuit means, the parts with which our circuit is made. For e.g.
A plug key, connecting wires, cell or battery, resistance or bulb, etc.
It’s the simplest circuit.
Components are generally the parts through which our circuit is made.
Here are the symbols of some components used in making circuits.
The simple circuit contains only the main components which should be in every circuit.
