Answer the following statement(s) true (T) or false (F)
1. With variable torque loads, the torque varies as the square of the speed. 2. The electronic shear pin reacts to the amount—and rate —of current increase to the motor. 3. The half-wave rectifier circuit requires two diodes and the use of a center-tapped secondary AC transformer. 4. In a three-phase rectifier system, the DC level remains high and the ripple percentage is very low; therefore, the DC supply needs very little filtering. 5. The armature power is typically controlled by an SCR that is turned on at different points in the waveform to adjust the voltage to the motor armature to control the speed.
