Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

If the resistance of any component in a parallel circuit changes, this will change the value of the current in that loop and the total current supplied by the battery. It does not affect the current ...
