AC SIGNALS - SQUARE WAVE, TRIANGULAR WAVE, SINE WAVE, COSINE WAVE, RECTANGULAR WAVE, ETC. SINUSOIDAL - SINE WAVE OR COSINE WAVE. WE KNOW THAT, INDUCED E.M.F = RATE OF CHANGE OF FLUX W.R.T TIME. SO, IF FLUX OR CURRENT (FLUX IS DIRECTLY PROPORTIONAL TO CURRENT) IS SINUSOIDAL, WE EASILY OBTAINED E.M.F. BECAUSE SINUSOIDAL WAVE ARE CONTINUOUS & EASILY DIFFERENTIABLE BUT NONSINUSOIDAL WAVES ( SQUARE, TRIANGULAR, RECTANGULAR WAVES) ARE DISCONTINUOUS IN NATURE & ARE NOT DIFFERENTIABLE.

Answer / sakthivel perambalur

your question is why ac signals are sinusoidal.

my answer is because generated emf is dynamically induced emf so AC signals are sinusoidal

A three phase load, around 4 km away from the 11/0.433KV distribution transformer (Neutral of Transformer is solidily earthed) and consisting of mainly very costly and sensitive electronic equipments is giving trouble due to high voltage difference between neutral and body earth. Whether this problem can addressed by connecting neutral at the load point solidly to earth?

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
