The series wound generator`s terminal voltage will, when below saturation
•  increase with an increase in load.
•  decrease with an increase in load.
•  decrease with a decrease in rotational speed.

A small air gap between magnetic poles results
•  in a weaker field than a large air gap, for the same magnetising force.
•  in a stronger field than a large air gap, for the same magnetising force.
•  in the same field as a large air gap, for the same magnetising force.
