Electrical Engineering Knowledge Test

Electrical Engineering Knowledge Test Summary

• Steel is difficult to magnetize due to its high density, high retentivity, and low permeability.
• Modern capacitors with high capacitance in small size use dielectrics such as paper, rubber, ceramic, or mylar.
• A diode is a nonlinear device.
• In a shunt generator, voltage builds up until it is constrained by speed limitation, armature heating, and saturation of iron.
• Slip rings in generators are made of materials such as steel, copper, bakelite, or mica.
• For proper parallel operation, AC polyphaser alternators must have the same speed, kVA rating, voltage rating, and excitation.
• The series field of a short-shunt compound DC generator is excited by external current.
• The reciprocal of permeability is reluctivity.
• The RMS value and mean value are the same for a sine wave.
• The maximum efficiency of a half-wave rectifier is 40.6%.
• 10 ergs/sec is equal to 0.00001 kW.
• The primary advantage of FM over AM is noise immunity.
