AC Generator working principle in tamil

(Sinusoidal Voltage)
A.C voltage or alternating voltage changes its polarity periodically and also changes its magnitude at every instant.
A.C Current:
(Sinusoidal current) An alternating current is a current which reverses its direction periodically and changes its magnitude at every instant.
Alternator:
An alternating current generator is called alternator. It works on the principle of electromagnetic induction.
An alternator is also called as AC Generator or synchronous generator. Working principle of alternator:
An alternator works on the principle of faraday’s law of electromagnetic induction. It states that when there is a relative motion between magnetic field and a conductor an e.m.f is induced in the conductor.
Alternating voltages / current may be generated by two ways:
1.By rotating a coil in a magnetic field.
2.By rotating a magnetic field within a stationary coil.
The quantity of voltages / current generated depends upon:
*The number of turns in the coil.
*Strength of the magnetic field The speed at which the coil of magnetic fields rotates.
*It is seen that the induced E.M.F. varies as sine function of the time angle t.
*This curve is known as sine wave and the E.M.F which varies in this manner is known as sinusoidal E.M.F. e = Em sinwt
Where,
e = Instantaneous voltage
Em = Maximum voltage
t = Angular velocity of the coil.
The induced sinusoidal voltages produce sinusoidal current.
These values are Im sinwt.
i = Im Sin wt
Where,
Im = Maximum value of alternating current.
Thank You for watching

Very very good explanation 👍👍👍👍👍🔥🔥🔥

[@muruganmass9958]

Super sir,why magnet doesn't work in south west direction,if any one will find south west like magnet another type of current generated I think,if the conducter is round shape can we get ac current

Sir
Na unga circuit theory lecture pakra rompa thelivana explanation sir
Na ithu varaikum maximum power transfer theorem varaikum pathuruken.. sir aptiye tellegan theorem pathium konja sollunga ..two port network aptina ena ? Konja details.. please sir..power system and machines also sir..elavarasan sir upload pannirukanga but nenga unga way of teaching la edutha nallarukum sir ..why because..nenga edukum pothu oru competitive exam prepare ahgura mathiri Ella explanation pnitu sum solve pnurenga ..exam ku practice ahguthu .aprom unit oda end la first la irunthu recall pnrenga.. athu two times padicha feel irukku..

Magnet pakkathula irukumpoothu thaanu maximum attraction irukum so diagram la 0° la thaanu maximum power kedaikum, 90° la irukum pothu magnet attraction kammithaanu aagum so appo power low thaanu aaganum...? Plz explain sir..

[@ragulprasanth3576]

Sir why we tell Alternating current ..why we not say alternating voltage
