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.
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.
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.
There are two main types of electricity: direct current (DC) and alternating current (AC). DC flows in one direction and is commonly used in batteries and electronics. AC changes direction periodically and is used in homes and businesses for powering appliances and lighting.
An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.
its commutator..which converts ac produced by and motor to pulsating dc ... more the commutator divide more accurate dc..means less pulse in dc
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)..
DC
Choice of electricity defines ac and dc
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.
Direct current
AC 220/240 volts
some things requre a dc (direct current) rather than an ac (alternating current)
the universel motor can runs at both ac and dc supply.
acdc is the best freakin' band ever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!but if your talkin about electricity that's good to
by blocking current flow in one direction
by blocking current flow in one direction
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.
