GUIDE
●● 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 non-inverting 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
