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:
