1.	If the students give a forward shift of 10° to the dc generator, then it _________(a) reduces flux per pole(b) improves flux per pole(c) increases the flux density in core(d) none of the mentionedThis question was posed to me in homework.My question is taken from DC Motor Starting topic in division DC Motors of Electrical Machines
Answer» Right choice is (a) reduces flux per pole For explanation: A generator given a FORWARD BRUSH shift will get its flux density REDUCED at the pole as the flux will be in the opposite DIRECTION.
