A Complete Electric Circuit

If the circuit isn t complete then there is nowhere for the electrons to.
A complete electric circuit. A circuit is a closed path that electrons flow along to provide power to your home and electronics. To be a circuit this path must start and end at the same point. Remember that the electrons that flow in an electric circuit are already there. It s best to think that charges just go round and round a circuit even flowing through the battery.
The point where the electrons leave an electrical circuit is called the return or earth ground. A complete circuit is a complete loop with electricity flowing the way it s supposed to flow. In other words a circuit must form a loop. From the battery to the component and back to the battery again.
In a circuit electrons flow from the battery through the wires and into the light bulb. 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. An electronic circuit is a complete course of conductors through which current can travel. An open circuit is an incomplete.
Circuits provide a path for current to flow. A simple electric circuit contains a power source battery wires and a resistor light bulb. The load is the amount of electrical energy the device uses to complete its task. An electronic circuit and an electrical circuit has the same.
