The AC circuits in which number of branches are connected in such a manner so that voltage across each branch is the same, but current flowing through them is different are called AC parallel circuits. The parallel circuits are used more frequently in AC system because of the following reasons:
- Almost all the electrical appliances (or devices) of different ratings are operated at the same supply voltage and are connected in parallel.
- Each device is required to be operated independently (with a switch) without disturbing the operation of other devices. Hence, they are connected in parallel.
