Electric Circuits

The current in a parallel circuit has at least two independent paths to flow. In this parallel circuit, the current can flow through each of the bulbs without having to first flow through any of the other bulbs. If a bulb fails, the other bulbs will continue to work because the current can still flow through the rest of the circuit. The brightness of the bulbs will not change, even if others are added to the circuit. Adding loads to a parallel circuit actually decreases the overall resistance of the current because the current has more paths it can travel through.
