Difference between alternating and direct current.
Answers
Alternating Current (AC)
Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.
Generating AC
AC can be produced using a device called an alternator. This device is a special type of electrical generator designed to produce alternating current.
A loop of wire is spun inside of a magnetic field, which induces a current along the wire. The rotation of the wire can come from any number of means: a wind turbine, a steam turbine, flowing water, and so on. Because the wire spins and enters a different magnetic polarity periodically, the voltage and current alternates on the wire. Here is a short animation showing this principle:

direction of current changes with regular interval
it can be transmitted for long time
can be changed to DC

direction of current will not change
cannot be transmitted for long time
cannot be converted to AC
