What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series ?

Advantages of connecting electrical devices in parallel are :

(i)In parallel circuits, if an electrical appliance stops working due to some defect, then all other appliances keep working normally and also each electrical appliance has its own switch due to which it can be turned on turned off independently, without affecting other appliances.

(ii)In parallel circuits,the same voltage(220V) from the power supply line would be supplied to each electrical appliance.

(iii)In the parallel connection of electrical appliances, the overall resistance of the household circuit is reduced due to which the current from the power supply is high.
