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.

How do you generate a sine wave?
A sine wave is generated by oscillating a periodic signal back and forth in a smooth, repetitive manner. This can be done using mathematical functions or by using electronic circuits like oscillators. The waveform of a sine wave is characterized by its amplitude, frequency, and phase.
Is AC a wave or a wave form?
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.
When the frequency in AC circuit is high the wave length is?
When the frequency in an AC circuit is high, the wavelength is shorter. This is because wavelength and frequency are inversely proportional in electromagnetic waves. As frequency increases, the wavelength decreases.
What is the difference between Vrms and Vpeak?
Vpeak is the maximum voltage measured in an AC signal, while Vrms is the root mean square value of the AC signal, representing the equivalent DC voltage that would produce the same heating effect in a resistor. Vrms is typically 0.707 times Vpeak for a pure sine wave.
What type of current is used in homes?
Both ac and dc current are used in our homes. But only low frequency (50 or 60 Hz) ac current is furnished by the power company. Electrical devices in our homes that require dc current usually have built in ac to dc rectifiers. we get electricity into home from main power supply as AC current.according to our electrinic devices select what type of current is suitable for it.for example,Ac power supply used to Tetevision,computers etc.Inside the devices,AC current convert into DC current.
