Question 1 of 10
What is the primary function of a diode?
A diode acts as a one-way switch, permitting current flow in only one direction (forward bias).
Question 2 of 10
Which terminal of a diode is typically considered positive?
The anode is the positive terminal of a diode.
Question 3 of 10
What happens when a diode is forward-biased?
When forward-biased, the diode allows current to flow.
Question 4 of 10
What should a good diode show in reverse bias when tested with a multimeter?
In reverse bias, a diode should block current and show high resistance, often indicated as OL on a multimeter.
Question 5 of 10
What is the typical voltage drop across a forward-biased silicon diode?
A forward-biased silicon diode typically has a voltage drop of 0.6-0.7V.
Question 6 of 10
Which multimeter mode is best used for the most accurate diode testing, according to the article?
Diode mode provides specific voltage drop readings, making it the most accurate.
Question 7 of 10
What would a defective diode typically show in reverse bias when tested with a multimeter in diode mode?
A defective diode might show low resistance, indicating current can flow in both directions (or a very low, non-zero resistance).
Question 8 of 10
Which of the following is NOT a characteristic of a diode?
Diodes do not amplify signals, while they are semiconductor devices, have two terminals, and pass current in one direction.
Question 9 of 10
What is the term for the negative terminal of a diode?
The cathode is the negative terminal.
Question 10 of 10
When testing a diode in resistance mode and the multimeter shows low resistance in both directions, the diode is likely...
Low resistance in both directions indicates the diode is shorted and therefore defective.
