What is alternating current?
Alternating current is an electric current that periodically reverses direction.

How is it produced?
It is produced by using a generator that reverses the direction of the magnetic field, continuously reversing the direction it flows as it is produced.

What are its advantages?
The major advantages of AC current over DC current is that it’s voltage can easily be raised and lowered using the transformers which cannot be used by DC, allowing for it to be transferred to far further distances away from the generator in a way that is still cost effective.



What is a direct current?
Direct current is the electricity that flow uniformly, that is, it flows in a single direction, and does not reverse.

How is a direct current produced?
Direct current is produced by the use of generators that, as the armature turns, do not reverse the current, making the current flow in a single direction. The generatos use turbines which use a wide range of resources. The materials used are:water in damns, air in windmills, heat from geotermal enrgy, steam from radioactive enrgy, burning coal, solar panels capturin the heat from the sun.

What is the difference between direct current and alternating current?
The difference is that in direct current the current always flows in the same direction while in alternating current the direction of the current reverses, or alternates.

Which one is most commonly used? Why?
<span style="font-family: 'Times New Roman',Times,serif;">the most commonly used type of current is AC, because it is possible to transport longer distances, making it more economically viable, since it's voltage can be raised for transfer and than lowered for usage.

<span style="color: #ff0000; font-family: 'Times New Roman',Times,serif;">What frequency is the current generated?
<span style="font-family: 'Times New Roman',Times,serif;">The current in which AC and DC is generated varies, as it is either used at a frequency of 50 or 60 Hz, depending on location, though it should be noted that 60Hz would be the better option.
