Is it AC or DC electricity in the home?

4 Answers

Answer :

In our home Ac Alternating current are supplied. Since our most of the load is Ac drive. Moreover in generating station Ac is produced .....

Answer :

In our homes we use AC. Since the main advantage of AC is its transmission, and AC can be step up and step down with the help of transformer. And generation of AC is cheaper and economical for large scale. The AC generator are cheaper and requires less maintenance. In our home there are mostly AC equipments like ceilings fan, air conditioners, washing machine, tube light, etc. So we use AC in our homes.

Answer :

A.c. current is only using in homes

Answer :

Obviously its A.C
