For domestic purposes, we connect the electrical devices in parallel instead of connecting them in series. What are the advantages of connecting devices in parallel instead of series?

Connecting electrical devices in parallel has many advantages.
  • In a parallel connection, voltage is equal for all elements. So, each device gets full or equal voltage. 
  • A device will not be affected by a disturbance in another device. If one device is switched off / on, other appliances remain unaffected. 
  • If one device is damaged, it is very easy to find the faulty device, as only a faulty device stops working.

All these advantages are lost if we use a series connection.
