Question
why we use only sine wave in ac why we do not use other wave
forms
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 11
It is easy to find
out phase difference
or phase angle in
sine wave than other
wave so sine wave is
used rather than
other wave

Answer
# 12
if we apply any wave form other than sine wave to the transformer the output is spikes due differentiation and devices dont work for those spikes and damage all home appliances so we use sine wave only

Answer
# 14
the nature of sine wave is exponentionally
increasing&decreasing,we know that any system components
can have some cutin voltage regions ,in that region the
system accepts slow +ve&-ve increasing&decreasing
sigals,every system contains semicondutor devices,because
of non linearity property of semiconductor ,the sine wave
has the same property.so it can be used.

Answer
# 15
actually the design of alternator which give power to us in
only for sinewave or cosine wave, bt when v use to generate
cosine wave only 3/5 of angle can rotae smooth...... coz
wile 2nd phase start it neutralise second so no resultant
force will be there for generation of power............
 
Is This Answer Correct ?    0 Yes 14 No

Answer
# 16
We use only sine wave as the voltage or current in A/C
system is continuously varying i.e reducing or increasing
at every small interval.
 
Is This Answer Correct ?    6 Yes 22 No
