Back pitch and front pitch are both odd and approximately equal to the pole pitch.<\/p>\n<p>The back pitch is the distance between the center of the pole face and the center of the armature winding, while the front pitch is the distance between the center of the armature winding and the center of the pole face. The back pitch and front pitch are both even numbers, and they are not necessarily equal to the pole pitch.<\/p>\n<p>The other options are all true.<\/p>\n<ul>\n<li>Compensating winding in a D.C. machine helps in commutation. Commutation is the process of transferring the current from one commutator bar to the next without sparking. The compensating winding helps to reduce the sparking by providing a path for the current to flow through during commutation.<\/li>\n<li>In a D.C. generator interpoles winding is connected in series with the armature winding. The interpoles winding is a small winding that is placed between the main poles of the generator. It is connected in series with the armature winding, and it helps to reduce the sparking at the commutator.<\/li>\n<li>Equalizing bus bars are used with parallel running of D.C. shunt generators. Equalizing bus bars are used to connect the armature windings of two or more D.C. shunt generators that are running in parallel. This helps to ensure that the current is shared equally between the generators.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Compensating winding in a D.C. machine helps in commutation&#8221; option2=&#8221;In a D.&#8221; option3=&#8221;generators is false?
