A complete electric circuit is basically an electric circuit in which the electrons flow from negative terminal to positive terminal without any disturbance. The switch has to be closed in order for this to work otherwise, the flow will be broken.
because with no circuit no current can flow.current is important in electricity to produce power to work.
Presenting the workings of a nerve as an electric circuit is a good way to explain by comparing and contrasting they way they both work, because they are similar and familiar.
If there is only one fan in the circuit then it is in a series circuit. If there is more that one fan then they will be connected in a parallel configuration.
Electric energy powers appliances such as a radio or light bulb. It travels in a CLOSE CIRCUIT.
The switch may be off or there is a break in the wire that stopped the electron flow in the circuit

Voltage causes current to flow in an electric circuit.
