12.
A diode for which you can change the reverse bias, and thus vary the capacitance is called a
varactor diode
tunnel diode
zener diode
switching diode
Answer: Option
Explanation:

13.
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:
there is a shorter time between peaks
there is a longer time between peaks
the larger the ripple, the better the filtering action
none of the above
Answer: Option
Explanation:
No answer description is available. Let's discuss.
14.
Testing a good diode with an ohmmeter should indicate
high resistance when forward or reverse biased
low resistance when forward or reverse biased
high resistance when reverse biased and low resistance when forward biased
high resistance when forward biased and low resistance when reverse biased
Answer: Option
Explanation:
No answer description is available. Let's discuss.
