(3BF-1.5)
What is the effect of an increase in ambient temperature on the
resistance of a carbon resistor?
C. The resistance change depends on the resistor's temperature
coefficient rating
*
(3BF-2.6)
What type of capacitor is often used in power supply circuits to
filter the rectified AC?
D. Electrolytic
*
(3BF-2.7)
What type of capacitor is used in power supply circuits to
filter transient voltage spikes across the transformer secondary
winding?
D. Suppressor
*
(3BF-3.5)
How do inductors become self-resonant?
C. Through distributed capacitance
*
(3BF-4.1)
What circuit component can change 1-VAC to 400-VAC?
A. A transformer
*
(3BF-4.2)
What is the source of energy connected to in a transformer?
B. To the primary winding
*
(3BF-4.3)
When there is no load attached to the secondary winding of a
transformer, what is current in the primary winding called?
A. Magnetizing current
*
(3BF-4.4)
In what terms are the primary and secondary windings ratings of
a power transformer usually specified?
D. Volts or volt-amperes
*
(3BF-5.1)
What is the peak-inverse-voltage rating of a power supply
rectifier?
C. The maximum voltage to be applied in the non-conducting
direction
*
(3BF-5.2)
Why must silicon rectifier diodes be thermally protected?
B. Because they will be destroyed if they become too hot
*
(3BF-5.4)
What are the two major ratings for silicon diode rectifiers of
the type used in power supply circuits which must not be
exceeded?
D. Peak inverse voltage; average forward current
*
