Refer to figure 1. If the load resistance
R2 is reduced by half what happens what
happens to zener diode?
Zener current will decrease
Refer to figure 1. The zener diode is de-
signed to breakdown at 6VDC what is the
voltage drop across R1 with a constant
DC supply of 10VDC
4v
An elevators motor rotates at 1200 rpm
at contract speed and is geard at a ratio
30 rpm 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?
Refer to figure 2. For the comparator cir-
cuit shown, what will happen to the out-
put of the non-inverting input goes more
positive than the inverting input?
The output will go to zero

Refer to figure 3. For the inverting op amp
shown, what is the output voltage?

Which term defines the limit of magnetic
Saturation strength around an inductor even though
the current through the coil increases
Voltage is removed from anode to cath- Which of the following describes how an
ode SCR is turned OFF?
On the fourteen pin DIP IC shown in
figure 4 what is the location of pin 14

A brake coil has an inductance of 4 hen-
ries. If the coil was placed into a circuit
1507 ohms
with an operating frequency of 60hz the
coil would have a resistance of:
The photodiode will conduct current
light
when it detects
