because in dc current is direct current and it continously varies. so it may be possible that some instrument may be damaged. so to avoid this first we have to convert dc to ac. Actually in our home dc is provided.suppose you want to charge your mobile than you have to convert first dc current to ac current.
AnswerAll homes are supplied with AC voltage. The reason for this is that the magnitude of an AC voltage is easily changed using a transformer, and it is easily changed into DC using a rectifier. Changing the voltage level of DC is far more complicated, as is changing it to AC.

∙ 8y agoHowever DC is used for safety in certain applications:
- electric doorbells operate on 6VDC to 24VDC
- some lighting operates on 12VDC
- etc.

∙ 8y agoA DC voltage is harder to manipulate when voltage changes are needed. This is because you can not use a transformer with a DC power supply. This is why an alternating voltage supply is used. AC can be generated at a low voltage, transformed to a very high voltage for transmission and then at the destination it can be transformed back down to a voltage that we all use in our homes. It is the transformation of the AC voltages that this type of system is used over a DC voltage.

Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
Why you should not use dc current in home?
That depends on you and the state of your home(clean, dirty, full of wood, unsatisfying conditions, etc.
Why can't we use DC supply in home?
in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.
Can you run fan on dc?
If you mean by that a normal home ceiling fan, No, you can't. Because it is an AC motor inside that. If you use fans using DC motors ,motors like the ones used in many toys for example or the ones used inside the earlier cassette or vcr tape drives, yes ,you can use DC.
Can you use dc motor to power hydro turbine?
no you can't use dc motor to power hydro turbine ?
Why not use DC power supply in home?
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
Why dc series motors cannot be used in home?

Which home appliances use a DC in their operation?
computer, t.v , radio etc
What is the output of the solar panel installed for the homes is it ac or dc?
It is dc but a small attached converter can make it ac for home use
Do all electrical home appliances use a DC supply and why?
Not all home applications are run exclusively by a dc current, ex: light bulbs Although some applications involve a dc current requirement such as battery chargers, computers and radios.
Why you should not use dc current in home?
That depends on you and the state of your home(clean, dirty, full of wood, unsatisfying conditions, etc.
Why you use ac current of home instead of dc?
alternating current is generally instantaneous in nature and even in transmission lines it is easy to transmit with less losses when compared to dc as because it possess frequency where as dc do not have
