AC power systems typically utilize which kind of waveforms?

AC power systems predominantly utilize sine waveforms due to their inherent properties that align with the principles of alternating current. Sine waves represent a smooth, periodic oscillation that effectively describes the behavior of voltage and current in AC systems. The sinusoidal shape allows for efficient energy transfer, minimizes power losses, and ensures that electrical devices operate smoothly and reliably.

Moreover, the natural characteristics of sine waves lead to less harmonic distortion, which can create interference and inefficiencies in systems using non-sinusoidal waveforms like square or triangle waves. Therefore, sine waveforms are the standard choice for AC power distribution, making them essential for both residential and industrial applications. This preference is also reflected in the design of generators and transformers that are optimized for sine wave output.
