600 Final Review Neiep questions with correct answers

600 Final Review 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: light - correct answer The photodiode will conduct current when it detects
