Overview A 6-V battery powers a circuit with parallel branches on a board. Several wires and light bulbs plug into the board to make various series and parallel circuits. The brightness of the bulbs ...

If one bulb burns out, all bulbs in the series will not light up. What is a Parallel Circuit? A parallel circuit allows electric current to flow through multiple paths simultaneously.

Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

In circuits connected in parallel, the components are connected on different branches. Find out more with BBC Bitesize. For students between the ages of 11 and 14.
