why we still use sinusoidal waveforms for transmission and
utilisation (we know generation is sinusoidal), instead of
other ac waveforms such as triangle, sawtooth, square etc.,?
is there any mathematical derivations to prove sinusoidal is
efficient than others?
Answer / venkata naidu
Its depends upon generator operation.whenever the conductor cuts the magnetic flux lines.it induces emf.this emf is depends on flux linkages.
THE FLUX LINES AND RECTANGULAR CONDUCTOR IN SAME AXIS.the emf is 0.again CONDUCTOR ROTATES SOME ANGLE. the emf is slightly increases. in this way the EMF WILL BE SLIGHTLY INCREASES AGAIN ITS SLIGHTLY DECREASES.
I.E, FINALLY GETS SINUSOIDAL WAVEFORM.

what is the formula for hv test for cable and circuit breaker..????
i have seen one 8.4 MW synchronous motor in a plant located in bellary it is fixed with brushless rotary rectifier ,anybody can explain its start up principle
according to faraday's law whether the induced emf is average or rms value?
I want to know how to calculate the size of electricity cable in building?

What is the equivalent circuit of a transformer and its vector diagram?
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
