Circuit that has only one path for the current to follow

Series circuit

Explanation:

The type of circuit can be divided into series and parallel. In the series circuit, there is only one loop/path. If the path is cut or stopped, the current of the circuit will be stopped completely. A parallel circuit has more than one loops. This means the circuit has alternative paths that it can travel in case that one path is blocked or cut. This alternative path makes the parallel circuit have a lower resistance compared to the series.
