Ac or alternating current is type of power delivery via electricty in which
|
||||||
|
the voltage is oscilated, usually using some form of sin wave.

== Power delivery ==
|
||||||
|
|
||||||
|
Power delivery is difficult to calculate for AC in comparison to DC. For DC,
|
||||||
|
the power delivery is calculated via
|
||||||
|
|
||||||
|
`P = E^2 / R`
|
||||||
|
|
||||||
|
For AC, however, we substitute E with the root mean square (RMS)
|
||||||
|
|
||||||
|
The RMS can be any value for different waves, however for the most common type
|
||||||
|
of wave, the sin wave, we can simply *multiply the peak voltage by 0.707*.
|
||||||
|
For example
|
||||||
|
|
||||||
|
Sin wave with a peak voltage of 17V has an RMS of 0.717 * 17 = 12V
|
||||||
|
|
||||||
|
To convert from the Power delivery of an AC line back to the peak power, simply
|
||||||
|
multiply the value by 1.414. For example
|
||||||
|
|
||||||
|
A 120V AC power line has a peak voltage of 120 * 1.414 = 169.7V
