All the alternators in our daily life generate Sinusoidal power which we use. Similarly can we generate Cosinusoidal power using our alternator? If it is then how it differs from a conventional generator?
If you are working at 50 Hz the answer is: wait 5 ms .
Cosinus is just a phase shift of sinus. A sinusoidal signal is, per definition, cosinusoidal, unless you have an absolute phase reference.
The difference between those functions is the phase. Specifically, cos(x) reaches its maximum value at t=0, but, as Carl says above, you need a phase reference (the initial phase mut be zero too)
Thank you Carl and Erick.....The difference is exactly what you said is in the phase angle.....My question is if I directly want to generate a Cosinusoidal power....how can we achieve...??
In power engineering we refer all the input voltages to be Sinusoidal of the form "VSin(wt)". It is so because the generation is of Sinusoidal nature. Similarly, if want to generate a Cosinusoidal power what changes has to be done in an alternator. If it is only about a reference why we take only Sinusoidal equations in AC power engineering......I hope I'm clear....
