Test One Flashcards
What are the two terminals of a semiconductor diode?
Anode and Cathode
What term is used to describe any external voltage that is connected to a diode?
The bias voltage
What does the triangle or arrow portion of a diode symbol represent?
The Anode terminal
What is the best way to describe how a diode operates in reverse bias?
It acts as an open switch
A diodes resistance increases as the diode voltage increases, true or false?
True
What will happen to a diode when the voltage applied to it exceeds the diodes PIV?
It will break down and fail
When testing a silicon diode with a DMM , what will the meter read if the diode will function properly when placed in a circuit?
Low V, O/L
If a silicon diode was connected to a 6 volt power supply with the (-) connected to the “P” type material and (+) connected to the “N” type material, what level of current would be likely to flow?
Only a small amount of leakage current
What is the most common use for a diode?
Rectification
What does it mean when you read O/L, O/L when testing a diode?
It indicates that the diode will not function
Diodes have a P-N junction that will not change resistance based on the polarity of the circuit and current flow through a resistive load, True or false?
False
What is the process of adding impurities to silicon and germanium to create a semiconductor called?
Doping
How do you find the VRL of a single phase 1/2 wave rectifier?
VRMS x .45
How do you find VRipple in a single phase 1/2 wave rectifier?
VRMS x .54
How do you find VRL in a single phase full wave rectifier?
VRMS x .9
