An electrical circuit is really a closed loop by which continuous electrical current goes from your supply to the load. If you are looking to describe a circuit for your friend or neighbor, chances are that you must draw the bond. For example, if you need to explain a lighting circuit, it can take added time to attract the bulb, battery, and wires because folks draw various components of the circuit in another way and this will take quite a long time to clarify. Therefore, a way is usually to learn how to show simple electrical circuits. In this article we provide drawings for a few simple electric circuits: AC lighting circuit, battery charging circuit, energy meter, switch circuit, air cooling circuit, thermocouple circuit, DC lighting circuit, multimeter circuit, current transformer circuit, and single phase motor circuit.
