Diodes and Applications Questions

• If a 169.7 V half-wave peak has an average voltage of 54 V, what is the average of two full-wave peaks?
• List three diode packages:
• When checking a diode, low resistance readings both ways indicate the diode is:
• With a 12 V supply, a silicon diode, and a 370-ohm resistor in series, what voltage will be dropped across the diode?
• A characteristic curve is the result of a current versus voltage plot of diode activity, which begins at the:
• What circuit activity may shift a characteristic curve so that diode operating points are different?
• What is wrong with this circuit?
• What is the current through the diode?
• One of the advantages of using transformer coupling in a half-wave rectifier is that it allows the ac source to be directly connected to the load.
• A zener diode can be tested with an ohmmeter.
• The forward biased characteristics of a zener diode are the same as those of a diode.
• If the diode in a series circuit is reverse biased, the resistor will drop all the applied voltage.
• A zener diode can be used to provide voltage regulation in a power supply.
• The number of electrons in a stable atom is the same as the number of protons in its nucleus.
• A zener diode has a larger breakdown voltage than a diode.
• The troubleshooting process for a typical dc power supply contains four steps.
• The diode's characteristic curve shows that current increases when voltage increases.
• An LED can be tested with an ohmmeter.
• The PIV rating of a diode in a full-wave bridge rectifier is more than that required for a full-wave center-tapped configuration.
• Dark current is a small reverse current that flows in a photodiode that is receiving no light.
