Question

why are parallel connection better than series connection in our houses

Answer 1

The house wiring should be done parallel because, in parallel connection there will be more advantages than a series connection.

Let a house is wired in series and it contains a fan, tube light, TV, refrigerator. All the devices are connected in series. Now, due to some disturbance the fan speed working or it burned. Then since the connection was a series, due to one appliance failure causes the whole circuit to fail. If it is burned that means it making an open circiut. Then there will be no current flow in the circuit.

Now if it was a parallel connection as we know already, the parallel connection is nothing but individual appliances connected to the same line by tappings. That means there's no dependency of one appliance on another. So if an appliance fail or burns it doesn't effects the remaining appliances. And there will be uninterrupted supply to the healthy appliances can be achieved.

So we use parallel connection for house wiring.

Answer 2

That is because, if series connection is used :

1. In order to use any one appliance, the current has to pass through all of them in a circuit and equally.

2. If any one appliance fails, since that portion of circuit is broken, the current will not pass beyond that point.
