Direct current commonly known as DC is the current which does not change it's direction of flow, but the magnitude can vary with time where as alternating current known as AC changes it's polarity with time it is not uni directional. the frequency of AC varies but DC donot contain such a feature it's frequency is zero.

What do Power supply symbols mean?
For instance, there is the difference between -direct current- and -alternate current- For example: a simple battery gives direct current, e bicycle-dynamo generates alternate-current, so plus becomes minus and vice versa several times a second. A symbol for direct current can be: ____ - - - A symbol for alternate current is a small sine-wave: ~
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 frequency of DC signal?
Zero = Nothing = Nil = 0 Hertz or Cycles per Second Direct Current is just as its name says: it does not alternate so it does not have any "frequency".
What device converts direct current to alternate current?
Any device that has a battery and can be plugged into the wall. The power coming from the battery is DC, while the power from the wall is AC.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.

Why does current alternate in our own power grid?
It's a decision based on efficiency of power transmission.
In electric terms what do the abbreviations AC and DC mean?
Its Alternate Current and Direct Current. I believe Angus Young got the idea for the band name when he say AC/DC on the bottom of his sisters sewing kit. Electric current can be direct current (DC) or alternating current (AC). Direct current such as the power from dry cells is characterized by a uniform direction of flow and amount (voltage) of electricity.
Is noise is a alternate current or direct current in a circuit?
Noise in a circuit typically consists of alternating current (AC) components, but it can also include direct current (DC) components depending on the source of the noise. AC noise may come from electromagnetic interference, while DC noise could be caused by sources like power supply issues.
What does the line below G in galvanometer indicate?
The Underline below symbol G represent about flow of current,if the line is straight it shows direct current,and if it is zig-zag then it is alternate current.
What is alternate current and direct current difference between?
Alternating Current (AC) is the type of electricity typically used in households. With AC, the magnitude and direction of electricity vary. Direct current (DC) is a source of electricity that does not vary in direction. An example of a DC source is a battery, or solar cells. The main difference between the two types of currents is simply the direction, as made quite clear by the names: AC = varied direction and magnitude where as DC = continuous current. Alternate current cannot stored but direct current can be stored examples in case of battery cells
Why doesn't all current move in the same direction?
Not all current flows in the same direction because electric energy does not follow the circular flow of electricity which results to direct and alternate current.
What does acdc mean in bad words?
Ac/Dc Orignally means Alternate Current/Direct Current. But, The name of the band AC/DC is "Anti-Christ/Devil's Child"
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 kind of current is California current?
Alternate current
What is an alternator for?
The alternator generates power to run the car and charge the battery. An alternator in a vehicle generates Alternate Current (AC) instead of Direct Current (DC) electricity to power the vehicle.
Why are alternate current motors easier to use than direct current ones?
In dc motor we need a complete kit of motor driving circuit whereas in af we only need a starter
