A Complete Electric Circuit

Any device attached to an electrical circuit that is activated or energized by the flow of electricity to it provides the electrical load on the circuit.

A complete electric circuit.

The point where the electrons leave an electrical circuit is called the return or earth ground. The load is the amount of electrical energy the device uses to complete its task. Remember that the electrons that flow in an electric circuit are already there. In a circuit electrons flow from the battery through the wires and into the light bulb.

In other words a circuit must form a loop. An electronic circuit is a complete course of conductors through which current can travel. The point where those electrons enter an electrical circuit is called the source of electrons. A complete circuit is a complete loop with electricity flowing the way it s supposed to flow.

An electronic circuit and an electrical circuit has the same. Circuits provide a path for current to flow. They come from the atoms that make up the wires so the wires are already full of electrons. From the battery to the component and back to the battery again.

A circuit is a closed path that electrons flow along to provide power to your home and electronics. A simple electric circuit contains a power source battery wires and a resistor light bulb. The exit point is called the return because electrons always end up at the source when they complete the path of an electrical circuit. An open circuit is an incomplete.
