A DC stands for DIRECT CURRENT. DIRECT CURRENT and VOLTAGE has constant amplitude at all time, hence there is no variations in its amplitude and has zero frequency. While the AC stands for Alternating current, which means the voltage and current varies with time. It has different Amplitude at different time. Due to variation it has some constant frequency, which is normally 50 or 60 Hz.

What is the difference between AC and DC choke?
There is no difference between AC AND DC chockes
What is the difference between ac and dc grounding?
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.
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What the difference between AC and DC?
AC rises with respect to time but DC is steady.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
Is ther any scientist proov that lightning is DC or AC?
Lightning is an impulse. If you wish to break it down mathematically, it is many AC signals summed together (Think Taylor series, or something similar). You can define DC in a similar light; perfect DC will be the summation of infinitely high to low frequencies. This is really a non-question. The very reasons to distinguish between DC and AC exist for other cases as well - such as impulses and switching.
Is DC is at low voltage than ac?
There's no correlation between the voltage, the current, and whether the source is AC or DC.

dc ammeter has three connecting pins while ac has four
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.

What is AC motor and DC motor?
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
