Answer / saurabh bhardwaj

IT DEPENDS UPON THE POLES IN THE D.C. MACHINE IF THERE ARE TWO
POLES IN D.C. MACHINE IT WORKS AS THE FULL WAVE RECTIFIER
IF WE INCREASE NUMBER OF POLES MORE THAN 2 THEN THERE IS A MORE
DC POWER IN COMPARISON TO FULL WAVE RECTIFIER
THE GENERATOR OUTPUT IS MORE SMOOTH THAN RECTIFIER

Answer / masoom raza
