Both ac and dc current are used in our homes. But only low frequency (50 or 60 Hz) ac current is furnished by the power company. Electrical devices in our homes that require dc current usually have built in ac to dc rectifiers. we get electricity into home from main power supply as AC current.according to our electrinic devices select what type of current is suitable for it.for example,Ac power supply used to Tetevision,computers etc.Inside the devices,AC current convert into DC current.
In the walls its AC.
Residential is normally AC supply, Schools etc can use both AC and DC based on the equipment used , supply to machinery etc for heating pumps and high usage machines and industry is normally three phase

Before Tesla contribution with his invention of alternate current, the electric monopoly was controlled by Thomas Edison. It was a direct current system and had to many problems like people getting shocked when touching the walls in their homes and many factories and homes burned by the current. Imagine if we continued increasing the use of direct current in homes all over the world.
AC (alternating current)
Direct current as would a magneto. For this reason it can be used with an integrated battery-condenser plant which would keep things going during slack periods.
