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.

What is alternating quantity?
An alternating quantity is a type of electrical current or voltage that periodically changes direction, moving back and forth. It is commonly represented as a sinusoidal waveform that alternates between positive and negative values. This type of electricity is used in household appliances and is generated by power plants.
What is double field theory?
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.

What is amplituide?
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..
Is it possible to measure power factor for dc system?
noAnswer'Power factor' is a quantity associated with alternating-current systems, and does not apply to direct-current systems'.
How can you measure ac?
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
Will 30 volts of supplied AC voltage produce the same current as 30v of DC through 2 kilo ohm resistance?
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?
"What is alternating current machine?"
Is reactance a scalar or a vector quantity?
In DC(direct current) circuits, voltage is scalar. But in the case of alternating-current(AC) voltage is vector quantity. It is because in an AC circuit the current is changing the direction for every time period. Therefore, since in this the direction matters its a vector quantity. Regards.
What is a graphical representation of alternating current?
The symbol for alternating current is: ~
What is current that keeps changing direction?
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.
