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.
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.
"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.
Alternating Current is measured in Amperes.
"Vector" is a description of magnitude and direction, and can apply to any quantity that has magnitude and direction, such as an aircraft's flight path. "Phasor" is a vector as used in alternating current electrical/electronic circuits. Calculations are the same as for general-purpose vector math, but the quantities are typically phase angle, voltage, voltage, current, resistance, reactance and impedance. Some calculations will use conductance, admittance and susceptance.
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.
