AC in this context probably means Alternating Current. This kind of current changes direction 60 times per second. The variation in the direction of the current can be graphed in the form of a sine wave.
An AC periodic wave refers to an alternating current waveform that repeatedly varies with time, switching direction at regular intervals. This type of wave is commonly used in electrical systems to generate power and transmit signals. AC periodic waves are defined by their amplitude, frequency, and phase characteristics.
Actinium
If you increase the frequency of a periodic wave, the wavelength would decrease. This is because wavelength and frequency are inversely proportional in a wave: as frequency goes up, wavelength goes down.
it is DC powered, but can generate sawtooth or triangular wave AC if wired up properly. it cannot generate sine wave AC, although with an opamp wave shaping circuit the triangular AC waveform can be reshaped to a rough approximation of a sine wave.
If its a triangular wave, its not DC, its AC, its just not sinusoidal. Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.
A pulse wave is a single vibratory disturbance that moves from one point to another. A periodic wave is a serious of disturbances that are evenly spaced.
AC stands for "alternating current," which is a type of electrical current that periodically changes direction. It is not a wave but can be represented by a waveform, which shows how the voltage or current changes over time in a repetitive manner. So, AC is not a wave itself, but it produces a waveform when graphed.
Wave is just a disturbance in a regular/periodic/organized way.
A periodic wave.
The velocity of a periodic wave is determined by the medium through which it travels and the frequency of the wave. Changes in the medium's properties (such as density or elasticity) can alter the wave velocity. Additionally, changes in the frequency of the wave can affect its velocity according to the wave equation.
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
Wave motion is considered doubly periodic because it repeats itself both spatially and temporally. In other words, the wave pattern repeats at regular intervals both in space and time. The spatial periodicity refers to the wave pattern repeating at a fixed distance, while temporal periodicity refers to the wave pattern repeating at fixed time intervals.
