Generation of sinusoidal voltage

 Generation of sinusoidal voltage:

 There are two facts that the voltage developed in a coil of a generator changes; the first one is it changes in magnitude from instant to instant as varying values of flux are cut per second and the other one is it changes in direction as coil side change positions under north and south poles, implies that alternating emf is generated. This means that the voltage is maximum as mentioned in our last topic here when the position of the coil is just like shown in the figure below

and will diminish to zero as the coil rotates clockwise toward the position as shown below: - See more at: http://electricalengineeringforbeginners.blogspot.in/#sthash.KN4iRb1Q.dpuf and will diminish to zero as the coil rotates clockwise toward the position as shown

                             

 

  

and will diminish to zero as the coil rotates clockwise toward the position as shown

Then, as the coil continues to rotate clockwise, the polarities will change. Assuming uniform flux distribution between north and south poles, the generated voltage in a coil located from the vertical will be

Then, as the coil continues to rotate clockwise, the polarities will change. Assuming uniform flux distribution between north and south poles, the generated voltage in a coil located from the vertical will be: - See more at: http://electricalengineeringforbeginners.blogspot.in/#sthash.KN4iRb1Q.dpuf
