ANSWERS TO QUESTIONS Q1. THROUGH Q24.
The left-hand rule for generators.
To conduct the currents induced in the armature to an external load.
No flux lines are cut.
The point at which the voltage is zero across the two segments.
By varying the input voltage to the field coils.
Distortion of the main field due to the effects of armature current.
To counter act armature reaction.
A force which causes opposition to applied turning force.
Resistance in the armature coils, which increases with temperature.
By laminating the core material.
Drum-type armatures are more efficient, because flux lines are cut by both sides of each coil.
Higher load currents are possible.
Series-wound, shunt-wound, and compound-wound.
Output voltage varies as the load varies.
It can serve as a power amplifier.
Gain = output ÷ input.
The mechanical force applied to turn the amplidyne, and the electrical input signal.
