NEIEP 600 FINAL EXAM 2026 COMPLETE PRACTICE TEST – 210+
MULTIPLE CHOICE QUESTIONS WITH ANSWERS AND
RATIONALES
Refer to figure 1. If the load resistance R2 is reduced by half what
happens what happens to zener diode? - correct answersZener current
will decrease
Refer to figure 1. The zener diode is designed to breakdown at 6VDC
what is the voltage drop across R1 with a constant DC supply of 10VDC -
correct answers4v
An elevators motor rotates at 1200 rpm at contract speed and is geard
at a ratio of 40:1. If the motor turns 40 rpm the sheave turns 1 rpm.

answers30 rpm
Refer to figure 2. For the comparator circuit shown, what will happen to
the output of the non-inverting input goes more positive than the
inverting input? - correct answersThe output will go to zero
Refer to figure 3. For the inverting op amp shown, what is the output
voltage? - correct answers-20 mv
, Which term defines the limit of magnetic strength around an inductor
even though the current through the coil increases - correct
answersSaturation
Which of the following describes how an SCR is turned OFF? - correct
answersVoltage is removed from anode to cathode
