Direct current and alternating current (or AC and DC) are forms of how the electrons are travelling. DC is when the electrons are constantly going out one end through the circuit and then to the other terminal, even if it takes different paths to get there it is still DC. AC is rather complicated; it is when the electrons are still flowing but generally don't have to go in the same direction, this is caused when the machine generating electricity uses magnets spinning inside a coil. When this happens it connects to two sides of the spinning magnet. When it spins the N and S parts of the magnets touch each measuring area. It always flows from the S to the N, this causes it to go in the opposite direction when it switches sides, creating alternating current.

"What is alternating current machine?"
The symbol for alternating current is: ~
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
alternating current electricity, or AC current, or AC.
Alternating current. Direct current is used in batteries.
Alternating Current is measured in Amperes.
Alternating current is better than direct current for transmission.
A generator produces alternating current.
Nicola Tesla is the father of alternating current.
It is technically an alternating current generator.It is technically an alternating current generator.
Alternating current (AC) is a type of electric current that changes direction periodically. It is commonly used in household electricity systems because it allows for easy voltage transformation and long-distance transmission.
