600 Final Review NEIEP Exam Questions With Accurate
Answers.
Zener current will decrease - accurate answers-Refer to figure 1. If the load
resistance R2 is reduced by half what happens what happens to zener diode?
4v - accurate answers-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

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 - accurate answers-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?
