(3BG-1.1)
Why should a resistor and capacitor be wired in parallel with
power supply rectifier diodes?
A. To equalize voltage drops and guard against transient voltage
spikes
*
(3BG-1.2)
What function do capacitors serve when resistors and capacitors
are connected in parallel with high voltage power supply
rectifier diodes?
C. They protect those diodes that develop back resistance faster
than other diodes
*
(3BG-1.3)
What is the output waveform of an unfiltered full-wave rectifier
connected to a resistive load?
D. A series of pulses at twice the frequency of the AC input
*
(3BG-1.4)
How many degrees of each cycle does a half-wave rectifier
utilize?
B. 180 degrees
*
(3BG-1.5)
How many degrees of each cycle does a full-wave rectifier
utilize?
D. 360 degrees
*
(3BG-1.6)
Where is a power supply bleeder resistor connected?
A. Across the filter capacitor
*
(3BG-1.7)
What components comprise a power supply filter network?
D. Capacitors and inductors
*
(3BG-1.8)
What should be the peak-inverse-voltage rating of the rectifier
in a full-wave power supply?
D. Double the normal peak output voltage of the power supply
*
(3BG-1.9)
What should be the peak-inverse-voltage rating of the rectifier
in a half-wave power supply?
D. One to two times the normal peak output voltage of the power
supply
*
(3BG-2.8)
What should the impedance of a low-pass filter be as compared to
the impedance of the transmission line into which it is
inserted?
B. About the same
