"What is alternating current machine?"
It is a common error with abbreviations when people use the abbreviation without knowing what the thing means - they end-up using the same word twice.People habitually say AC current as well, and AC volts which is really nonsense too. It is just habit and convention and is not restricted to science/technical terms.Additional AnswerIn fact, this is not an error at all. In electrical engineering terminology, the abbreviation, a.c., is considered to be an adjective. So it is both grammatically and scientifically correct to use the expressions "a.c. current" or "a.c. voltage". Of course, if you choose not to use the abbreviation, 'a.c.', then you should say or write "alternating current" or "alternating voltage".
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. Direct current is used in batteries.
Alternating Current is measured in Amperes.

A generator produces alternating current.
Nicola Tesla is the father of alternating current.
