What is AC Power? AC stands for alternating current, which means the electrical current frequently reverses direction. AC electricity is measured according to its cycles, with one complete cycle being counted each time a given current travels in one direction and then doubles back on itself.
Thereof, what is the most common type of AC waveform?
If we hook up an oscilloscope to a circuit with AC and plot its voltage over time, we might see a number of different waveforms. The most common type of AC is the sine wave. The AC in most homes and offices have an oscillating voltage that produces a sine wave.
What is alternating current waveform?
The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves.
Why sine wave is used for AC supply?
Now in general, in a AC generator, the rotating motion (steady rotation) of the magnetic rotor leads to sinusoidal variation of generated voltage in the winding of the stator and consequently in any circuit which is connected to the output. Thus sinusoidal is taken as the best convention to represent AC quantity.
