Question 1 of 5
In forward bias, how is the P-side of a PN junction diode connected to the external voltage source?
In forward bias, the P-side (positive) is connected to the positive terminal of the voltage source.
Question 2 of 5
What happens to the depletion region width when a diode is forward-biased?
Forward bias reduces the width of the depletion region, facilitating current flow.
Question 3 of 5
Approximately what voltage is required to forward bias a silicon diode?
Silicon diodes typically require around 0.6V to overcome the barrier potential and begin conducting.
Question 4 of 5
In reverse bias, what is the primary effect on current flow through the diode?
Reverse bias effectively blocks current flow, allowing only a tiny leakage current.
Question 5 of 5
What happens to the depletion region width when a diode is reverse-biased?
Reverse bias increases the width of the depletion region, inhibiting current flow.
