It's any quantity that changes in a regular and repeating fashion, and when you
draw a graph of its variation with time, or view it on an oscilloscope or computer
screen, the graph has the same shape as the trigonometric 'sine' function of angles.
You'd recognize it immediately if you saw it.
alternating quantity is a quantity that is alternating
The double field revolving theory states that, any alternating quantity can be resolved into two rotating components, which rotate in opposite directions and each having a magnitude as half of the maximum magnitude of the alternating quantity.

amplitude can be defined as the maximum value of varying quantity . the varying quantity can be an alternating one or distorting. graphically speaking the maximum value of the curve within the extremes of a domain is called as the amplitude..
noAnswer'Power factor' is a quantity associated with alternating-current systems, and does not apply to direct-current systems'.
AC, or alternating current.AC, or alternating current.AC, or alternating current.AC, or alternating current.
Yes. Because the 30v ac is root-mean square value which is the value of an alternating quantity that will produce the same heating effect as the DC quantity when applied to the same resistance.
"What is alternating current machine?"
you can measure ac using a cathode ray oscilloscope. it will project a sinusodial waveform, showing that the current is in the positive direction in the first half and the opposite direction in the second half
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
The symbol for alternating current is: ~
