An electrical circuit is a path which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".

A battery, a light bulb and a switch
A simple electrical circuit consist in a source of power (like a battery), a conductor (like a wire), and a load (like a light bulb, a motor, a resistor, etc)
Simple parts of a circuit are switches, light bulb, battery and connecting wires.
The drawing of an electrical circuit is called a circuit diagram, or schematic diagram. It is a graphical representation of the electrical components and their interconnections in a circuit. It uses standardized symbols to represent different components such as resistors, capacitors, transistors, switches, and wires. The lines connecting the symbols in the diagram indicate the flow of electrical current through the circuit. Circuit diagrams are used to design, troubleshoot, and repair electrical systems, and can be found in technical manuals, books and online resources.

Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
