Explain how the current through a diode changes as the reverse bias voltage approaches and exceeds the reverse breakdown voltage (V_Rmax).
19
Multiple Choice
What is the significance of the reverse breakdown voltage (V_Rmax) in a diode's operation, and what happens when the reverse bias voltage exceeds this value?
The diode continues to operate normally as a one-way valve.
The current decreases rapidly in the reverse direction.
The diode may be damaged and will no longer operate as a one-way valve.
The forward voltage drop increases.
