a control rheostat directly across the supply. It is therefore in
parallel with, or shunting, the armature.
The field current is independent of the armature current unless
this is large enough to cause a voltage drop in the supply lines in
which case both the armature voltage and the field voltage will be
Series Figure 6.25 shows the series connection. The field winding com-
prises a few turns of very heavy gauge wire or copper strip. It is con-
nected in serie
