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.
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.
Non load bearing walls are walls that the weight of the roof is not supported on. Any wall that runs parallel will roof joists will be non load bearing.
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
used as wave form generators like sinusoidal and non sinusoidal,
because they have more harmonics
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
Sinusoidal current is not true of sinusoidal current.
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.
There is a problem called "neutral phase shift" in star-star transformer, if we connect unbalance load(single phase load at secondary), then the phase point is shifted towards neutral. we require sinusoidal secondary voltage at secondary, for this flux must be sinusoidal. Flux will be sinusoidal, if it contains the third harmonic component of exciting current. so third harmonic current can not flow in star-star transformer. so we use delta-star transformer,in delta , third harmonic component can flow & get sinusoidal output.
