Meaning

A Parallel Circuit is an electrical circuit with two or more paths the current can flow along.

About Parallel Circuits

In a paralle circuit the current is split at the junctions.

Components placed in parallel with each other have the same Potential Difference across them.

Examples


The cell, bulb and Voltmeter are in parallel so they have the same Potential Difference across them.	The two bulbs are in parallel so they have the same Potential Difference across them but may have a different Current passing through them.	The bulb and motor are in parallel so they have the same Potential Difference across them but may have a different Current passing through them.
