Question

when a diode is forward - biased and the bias voltage is increased, the voltage across the diode (assuming the practical mode) will

Explanation:

Step1: Recall diode forward - bias practical model

In the practical model of a forward - biased diode, once the diode is forward - biased and the bias voltage is increased beyond the cut - in voltage (for silicon diodes \(V_{on}\approx0.7V\), for germanium diodes \(V_{on}\approx0.3V\)), the voltage across the diode remains approximately constant.

Answer:

stay the same
