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".
"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. Direct current is used in batteries.
DC stands for direct current in physics. It is a type of electrical current that flows in one direction consistently throughout a circuit. This is in contrast to alternating current (AC), which changes direction periodically.
Alternating Current is measured in Amperes.
Alternating current is better than direct current for transmission.
A generator produces alternating current.
