- The power transmission would require bigger wires to transmit high dc current so instead high voltage ac current is transmitted through long distance lines
- To reduce losses it is necessary for the value of current through lines to be low
- Tranformers donot work for dc current so one cant step up and step down dc current voltage like it can be done with ac current

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.
What is the use of a regulator?
ac supply converted with dc supply
What is the use of regulator?
ac supply converted with dc supply
How do you generate ac supply?
AC supply is generated using alternators, which convert mechanical energy into electrical energy. This process involves rotating a coil within a magnetic field, inducing an alternating current due to electromagnetic induction. Power plants typically use turbines driven by steam, water, or wind to turn the alternators, producing the AC electricity that is then distributed through power lines for use in homes and businesses. Additionally, inverters can convert DC (direct current) from sources like solar panels into AC supply.
How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
What type of current is used in homes?
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.
Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
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
Why less loss occurs when you use DC supply than AC supply?
There are less loss occurs when we use DC supply than AC supply, because the frequency is zero in DC, so no Inductance & Capacitance exists.And there is no skin effect in the DC systems, so there is low resistance as compared to AC systems.Rac = 1.25*Rdcfrom Arun Kumar SRR
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
Is the power line voltage available in your homes a DC or an AC voltage?
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
