paratively few turns, which should be of correspondingly large wire, in order that the watts loss (which is equal to C2R) should be kept within the desired limits.
It will be seen that in series-wound dynamos the difference of potential between the terminals of the machine is less than that which appears between the brushes by the amount of the drop in the magnetizing coils.
The above remarks concerning the magnetizing coils of shunt and series wound dynamos also apply to those of compound-wound machines, since they are made up of a shunt and a series winding.
