DC, the electron flow is in one direction, from the negative terminal to the positive terminal, or, conventional current flows from the positive terminal to the negative terminal. But in any case the current flows in one direction only.
AC, the direction of the current flow reverses 120 times a second (for 60 Hz power) or at some other rate, with the voltage (or current) flow following a sine wave as it goes through zero, up to a positive peak, back through zero to a negative peak, then back to zero, for one cycle.
The advantage of AC is that you can use Transformers to efficiently change the voltage to various levels, high voltage for efficient power transmission, and safer lower voltage for house distribution, and even lower voltage to power electronics (after conversion to DC).
AC is power from an alternator ,, the voltage fluctuates between =120 volts and +120 volts .. DC is direct and is typically supplied by a battery
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
AC power is made by alternating current and DC does not change.
There is no difference between AC AND DC chockes
The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.
AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.
in electronics we use DC current but in elctrical equipment we use AC current
Yes, there is. AC = Alternating Current, the direction of the current alternates, thus the name. DC = Direct Current. Things like computers need DC (they use a AC to DC converter inside the power supply to convert it) Hope that helps a bit.
if ac changes direction then how current happen to flow
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
The differenece is in the type of current it uses. AC is usually what is used in the home and DC from something like the car battery.
1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.
