Three resistors are used in the Parallel Circuit, however they form more than one continuous route for current to travel. A parallel circuit is distinguished by the fact that all components are linked to the same set of electrically common terminals.

In a series circuit, the amount of current flowing through each component is the same. This is due to the fact that in a series circuit, there is only one channel for current to flow.
