Give two reasons why different electrical
appliances in a domestic circuit are
connected in parallel?

Answer :

The arrangement of lights and various other electrical appliances in parallel circuits is used in domestic wiring because of following advantages:
In parallel circuits, if one electrical appliance stops working due to some defect, then all other appliances keep working normally.
In parallel circuits, each electrical appliance has its own switch due to which it can be turned on or turned off independently, without affecting other appliances.
