Which statement best explains why household electrical appliances are connected in parallel rather than in series?
Each appliance receives the full supply voltage and operates independently.
In a parallel arrangement each branch is connected directly across the same pair of supply terminals, so every appliance always gets the full mains voltage (about 220 V in India) irrespective of what else is switched on.
Each appliance also has its own separate current path; therefore switching one on or off, or a fault in one, does not interrupt the others – they operate independently, which is essential for a home circuit.
In a series circuit the same current would pass through every device, the voltage would be divided between them, and a failure or switching off of any one would break the whole circuit – clearly unsuitable for household use.
Hence, the answer is that each appliance receives the full supply voltage and operates independently.
