Commutation in a DC machine may be explained as a process
A. in which magnetic field is set up.
B. by virtue of which EMF is induced in the armature conductors.
C. by which current in a coil is reversed during the period it is short circuited by the brush.
D. how armature flux affects the main field flux.
