Direct current runs in one direction.
Alternating current actually changes direction at a rate of 60 cycles (called Hertz, or Hz) a second in the United States and 50 cycles in Europe. A cycle is once in each direction. It's hard to imagine an object changing directions 120 times a second but this is what happens.
We still talk of AC as flowing to a load in one wire and returning in another, which is what DC really does. And in your home or office this simplifies a rather complicated process. But in reality the electrons never flow that far before they turn around a go back the other way.

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 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
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.
Why does current alternate in our own power grid?
It's a decision based on efficiency of power transmission.
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.
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.
What is deference between will you and would you?
Would implies a conditional intent, e.g. "I would IF....", whereas will indicates direct, unconditional intent.... I think...
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.
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 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
