a.c. generator converts mechanical energy to electrical energy. work on the of electromagnetic induction.can you mark it in BRAINLIST QUESTION
yes
their
we have heavy rain and flood
by 5 more water from dam will be given out so we are given emergency allert.

An Electrical Generator is a device that produces an Electromotive Force (e.m.f.) by changing the number of Magnetic Flux Lines (Lines of Force), Φ, passing through a Wire Coil. Figure 1 is one type of Generators. When the Coil is rotated between the Poles of the Magnet by cranking the handle, an AC Voltage Waveform is produced.
Operation principle of a Generator is based on Electromagnetic Induction, which is defined by Faraday’s Law, which states:
The Electromotive Force, Eemf, induced in a Coil is proportional to the number of turns, N, in the Coil and the Rate of Change, dΦ / dt, of the number of Magnetic Flux Lines, Φ, passing through the surface (A) enclosed by the Coil.
An Induced Effect is always such as to Oppose the cause that produced it.
In the Generator, the Coil is under a Stationary Magnetic Field. The Magnetic Flux Density, B, is constant and Φ = B x Aeff, so Φ is proportional to the Effective Area, Aeff, of the Loop. As the Loop rotates at different angles, there is a change in Aeff
