600 FINAL REVIEW NEIEP QUESTIONS
AND ANSWERS
Zener current will decrease - correct answer- Refer to figure 1.
If the load resistance R2 is reduced by half what happens what
happens to zener diode?
4v - correct answer- 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
30 rpm - correct answer- 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. What is the actual
speed of the drive sheave in rpms?
The output will go to zero - correct answer- 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?
-20 mv - correct answer- Refer to figure 3. For the inverting op
amp shown, what is the output voltage?

Saturation - correct answer- Which term defines the limit of
magnetic strength around an inductor even though the current
through the coil increases
Voltage is removed from anode to cathode - correct answer-
Which of the following describes how an SCR is turned OFF?
Top right - correct answer- On the fourteen pin DIP IC shown in
figure 4 what is the location of pin 14
1507 ohms - correct answer- A brake coil has an inductance of
4 henries. If the coil was placed into a circuit with an operating
frequency of 60hz the coil would have a resistance of:
light - correct answer- The photodiode will conduct current
when it detects
A relay timer - correct answer- What does the circuit in figure 5
represent?
