A load that is not sinusoidally varying (i.e. resembling that of a graph of the function sin(x) or cos(x)). This means the load is not cycling or periodic so it does not repeat itself over and over - which is exactly what the graph of the trig function sin(x) demonstrates.
sinusoidal vs non sinusoidal
sinusoidal with non-zero average.
Sinusoidal loads are preferred over square loads primarily due to their smoother waveform, which results in less harmonic distortion and reduced stress on electrical components. This leads to improved efficiency and lower heating in both the load and the power system. Additionally, sinusoidal loads facilitate easier analysis and control in AC systems, making them more compatible with standard power generation and distribution methods. Overall, they enhance system reliability and performance.
because they have more harmonics
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
sinusoidal vs non sinusoidal
eddy current loss in the transformer core is reduced by

excitation voltage is sinusoidal because it is taken from the terminal of alternator but excitation current is non-sinusoidal because it always dc.
sinusoidal with non-zero average.
No load current is mostly inductive, hence the load current may not be a sine wave

the process of producing non sinusoidal output waves from sinusoidal input is cald non linear wave shaping.. the circuits of this sort are called non linear wave shaping circuits.. they are of two types.. clippers and clampers
The input current of a transformer is non-sinusoidal primarily due to the presence of non-linear loads connected to the transformer, which introduce harmonics into the system. Additionally, the transformer itself can exhibit non-linear characteristics, especially when operating near saturation or under varying loads. These factors result in a distorted current waveform that deviates from a pure sinusoidal shape, leading to increased losses and potential overheating in the transformer and connected equipment.
RMS power is Peak-To-Peak power divided by the square root of 2.This definition, however, only holds true for a non-reactive, or resistive, load, with a power source that is truly sinusoidal.
