in alternator the voltage and current produced varies with
respect to time as represented by sinewave That is why it
is represented as sine wave We cant produce voltage other
than sinesoidal waveform from alternator However if produce
whichever form of waveform required using electronic
components and by properly designing the circuit

Answer / virendra j joshi

Beacause in AC voltage , the voltage increses from ZERO to
MAX gradually also Maz to zero .

The same way Zero to -Max & -Max to zero

This is happen gradull, as voltage in AC circuit for 1
cycle does not remain a same for even a short period of
time. that is the reason why we consider it sinusodial
insted of sqqure or rectungular.

Answer / khs kumar

I Agree with Mr. Virendra J Joshi.
In case of Square Wave the voltage will not vary with time. There will be only two stages one is saturation point and the other is cutoff point. This can be happened only in DC voltage. When the power is on then it will reach to saturation point and be stable unless until it is off. Once it is off it will reach to cutoff point and be stable unless until it is on. One completion of on stage and offstage is called one complete cycle.

Answer / arun

boz all second order sysem Responses are sinusoidal waveform
and it is easy to generate.
or
integeral and differential of sine is sine wave

Answer / sujith chowdary

being easy to use for calculations, the most popular
waveform is sinusoidal waveform

Answer / manilal.r

Sine wave mens it can
produce a continuity,or it is
a continuos time sigal.its
have a value when all the
time of "t".....
electricity is a continuos
nature,so when we feeding
electricity one point to
another it is very
necossory to have a
continuos form! that is why
when we prefers
electricity have been a sine
wave
