Question

Why is parallel arrangement used in domestic wiring?

Answer 1

Parallel arrangement is used in domestic wiring because of the following reasons -

1.  Net resistance of the electric circuit decreases in parallel connection as compared to series connection due to which heat loss is reduced.
2. Potential difference across each electrical device remains same i.e 220 V due to which all the electrical devices work upto their maximum potential.
3. Each electrical device can be operated independently.
4. If one electrical device stops working still other electrical devices continue to work properly.
