A parallel circuit is an electrical circuit which has two or more paths for an electrical charge to flow through.The parallel circuit is the standard electrical circuit found in most homes and devices.Because it provides more than one way for a current to flow through to a device, it creates a much more stable and efficient power system than would otherwise be possible. The uses of the parallel circuit are manifold.arallel circuits are used inside many electrical devices and appliances. The main reason parallel circuitry is used in this context is to take advantage of more than one power source, like when more than one battery is being used in a portable device.
In many electronic circuits series resistors are used to get a different voltage across one of the resistors. We'll look at those circuits, called voltage dividers, in a short while. Here's the circuit diagram for a voltage divider.
