GRADED A+
◉ 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 Answer: 4v
◉ 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? Answer:
30 rpm
◉ 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? Answer: The output will go to zero
◉ Refer to figure 3. For the inverting op amp shown, what is the
output voltage? Answer: -20 mv
, ◉ Which term defines the limit of magnetic strength around an
inductor even though the current through the coil increases Answer:
Saturation
◉ Which of the following describes how an SCR is turned OFF?
Answer: Voltage is removed from anode to cathode
