In a power supply diagram, which block indicates a pulsating dc output?
Since diodes are destroyed by excessive current, circuits must have:
Providing a constant output regardless of ac input or load resistance changes is the function of a:
When a diode is forward biased, the voltage across it
Which of the following circuits would require the least amount of filtering?
With a 12 V supply, a silicon diode, and a 370-ohm resistor in series, what voltage will be dropped across the diode?
Shunting the ac component away from the load is the task of a:
List three diode packages:
A diode for which you can change the reverse bias, and thus vary the capacitance is called a
A filtered full-wave rectifier voltage has a smaller ripple than does a half-wave rectifier voltage for the same load resistance and capacitor values because:
When a diode is destroyed it has infinite impedance. When damaged by heat it will probably:
The characteristic curve for the complex model of a silicon diode shows that
Why is heat produced in a diode?
The arrow in the schematic symbol of a diode points to
What is a varistor?
An LED can be tested with an ohmmeter.
A rectifying diode can change ac voltage to dc voltage.
Atoms in a silicon crystal are held together by ___ bonds.
If the frequency of the applied ac signal to a half-wave rectifier is 60 Hz, the frequency of the pulsating dc output will be
A pn junction allows current flow when
