Why is a series arrangement not used for connecting domestic electrical appliances in a circuit?
Advertisements
उत्तर
A series arrangement is not used for connecting domestic electrical appliances because different appliances have different resistances; this leads to the problem of unequal voltage distribution. Another reason why this arrangement is not preferred is that if one of the appliances gets damaged, the power supply to all other appliances is cut off.
