In the case of AC, you can express the current, the voltage and the equivalent to the resistance (called "impedance" in this case) as a vector - with a magnitude, and a phase angle.
"What is alternating current machine?"
That refers to AC (alternating current). A direct current flows only in one direction; an alternating current changes its direction all the time. The "frequency" refers to how often the current changes direction. It is expressed in hertz (Hz), which means the same as cycles/second.
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.
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.
A current which changes its direction of flow again and again is known as alternating current.
