current comparison

Current and voltage behave differently in series and parallel circuits.

In a series circuit, the current remains the same around the circuit, but the voltage is split between the circuit components.

In a parallel circuit, the voltage remains the same around the circuit. But the current is split between the different branches.

If you connect more light bulbs in a series circuit they get dimmer. This is because voltage is split up between components in series circuits. This means that when more light bulbs are added, each light bulb has less voltage across them. Less voltage results in a dimmer light bulb.

light bulb brightness does not change in parallel circuits. This is because voltage is divided equally in parallel circuits, so each light bulb has the voltage across it when they are added in parallel.

We can use switches to control individual circuit components in parallel circuits. This is because a switch on a branch will only affect the components on that branch.
