Home Electricity is Alternating Current (AC). AC can be transmitted much longer distances, over much less massive conductors than direct current (DC).
CommentActually, d.c. can be transmitted much longer distances, with less massive conductors and lower losses, than a.c! However, the reason that a.c. is more common for transmission and distribution is the ease and efficiency with which its voltage levels can be changed using Transformers. D.C. transmission at high voltage over very long distances is used because it is much more efficient than a.c. transmission, but changing its voltage levels is far more difficult and inefficient compared with a.c.

∙ 13y agoThe electricity supply in UK is definitely AC (Alternating Current). It is produced at a high rated voltage before it is transferred across the country on pylons, and then it is stepped down to 415 volts ac. Before it enters a house it is stepped down to 240 v .
Supply sockets have three holes, one for live , one for neutral and one for the earth safety conductor .

∙ 9y agoIn the US (and, as far as I know, worldwide) electrical outlets supply alternating current. AC has superior transmission characteristics, making it more efficient.
Comment
Actually, d.c. has much superior transmission characteristics compared with a.c. However, it's much easier to increase/decrease the levels of a.c. voltage using transformers.

∙ 12y agoThe best answer is that it is both. However there is still some debate on the subject.

Is home electricity in the UK ac?
no ! ................
Do phones use ac or dc?
Some devices operate on AC and others on DC. Generally, anything that uses mains electricity (120V US, 240V UK) is using AC electricity and things that use batteries or are rechargable like cell phones, ipods, personal CD, use DC electricity.
What are the advantages of AC and DC electricity?
AC electricity will not dissipate in charge traveling along a wire for up to hundreds of miles whereas DC dissapates at about 2 miles at its best. DC is simple and easy, the simplist electrical cirtuit possable.
Does a light switch produce AC or DC electric currents?
Alternating (AC) and direct (DC) currents are different forms of electricity. It is universal nowadays to have AC in all houses because the electricity grid distribution system is all AC. DC was used by Edison and continued for some years but is now discontinued. It is still used in vehicles where 12 V DC is the normal system. A light switch simply interrupts the current or makes the circuit as required, and both AC and DC need to have switches.
What is an electrical capacitor?
Electricity is either alternating current or direct current, abbreviated AC or DC. An AC/DC Capacitor can be used in either an AC or DC current.
Is electricity AC Or DC currant which one?
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
Car electricity uses ac or DC?
DC
Which choice defines AC and DC correctly?
Choice of electricity defines ac and dc
What doaes ac DC stand for?
The two forms of Electricity are AC and DC. AC Stands for Alernating Current and DC stands for Direct Current. AC electricity comes out of the Powerpoint that your computer is probably using and DC electricity is used in 5.1 voltage batteries that probably power your flashlight or toy.
Is the electricity from batteries AC or DC?
Direct current
Is home electricity in the UK ac?

acdc is the best freakin' band ever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!but if your talkin about electricity that's good to
How do diods convert AC electricity to DC electricity?
by blocking current flow in one direction
How do diodes converts ac electricity to dc electricity?
by blocking current flow in one direction
Is it diesel generators is DC or AC generators?
Most diesel generators are designed to produce alternating current (AC) electricity. However, there are some diesel generators that can also produce direct current (DC) electricity with the help of rectifiers or inverters.
Do phones use ac or dc?
