ACE 2026/2027 NEIEP 600 FINAL EXAM: COMPREHENSIVE
QUESTIONS AND ANSWERS GRADED A+
⩥ 4v. 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. 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. Answer: Refer to figure 2. For the
comparator circuit shown, what will happen to the output of the
noninverting input goes more positive than the inverting input?
⩥ -20 mv. Answer: Refer to figure 3. For the inverting op amp shown,
what is the output voltage?
⩥ Saturation. 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. Answer: Which of the
following describes how an SCR is turned OFF?
⩥ Top right. Answer: On the fourteen pin DIP IC shown in figure 4 what
is the location of pin 14
, ⩥
⩥ 1507 ohms. 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. Answer: The photodiode will conduct current when it detects
⩥ A relay timer. Answer: What does the circuit in figure 5 represent?
⩥ 12.5 A. Answer: A string of temporary lighting has fifteen 100 watt
bulbs. A 15 amp breaker is the maximum size that can be used with the
14 gauge wire used in this 120 volt circuit. What is the current?
⩥ 4.61 henries. Answer: If a circuit has three inductors in parallel of 10,
15, and 20 henries, what is the total inductance?
⩥ LED. Answer: What does the symbol in figure 6 represent?
⩥ A .7V drop from base-to-emitter is an indication of a good junction.
Answer: Which of the following statements is correct when testing
transistors?
⩥ An SCR. Answer: What does the symbol shown below represent?
