An

**electric 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.In a series circuit, the

**current**through each of the**components**is the same, and the voltage across the circuit is the**sum**of the voltages across each component. In a parallel circuit, the voltage across each of the**components**is the same, and the total**current**is the**sum**of the currents through each component.
