How does an A.C Generator work?
Please help
Thanks
Answer:
The turning of a coil in a magnetic field produces motional emfs in both sides of the coil which add. Since the component of the velocity perpendicular to the magnetic field changes sinusoidally with the rotation, the generated voltage is sinusoidal or AC. This process can be described in terms of Faraday's law when you see that the rotation of the coil continually changes the magnetic flux through the coil and therefore generates a voltage.
So that means you have time to study, rather than just try to get someone to tell you how it works. I'd try looking in the textbook first.
Basically you have a coil which is turned through a magentic field by some form of other engery, hydro, gas powered, etc. The field passes energy in the form of electrical current through the coil which results in a sinisodial wave output of current. The link below has it in detail.
