ANSWER-Which statement is correct regarding capacitors?
Dielectric - CORRECT ANSWER-Which of the following factors determines the
voltage rating of a capacitor?
, A resistor is placed in series with the capacitor - CORRECT ANSWER-What is
usually done to protect large capacitors during charging?
Excessive current in the coil circuit - CORRECT ANSWER-An MOV placed
around a relay coil for voltage spike suppression has shorted. What would the
effects be?
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?
