The second approximation of a silicon diode is basically
A) the diode appears as a switch in series with a barrier potential of 0.7 V.
B) the diode appears as a switch in parallel with a barrier potential of 0.7 V.
C) the diode appears as a barrier potential of 0.4 V.
D) the diode appears as a short circuit.

Question

Quizplus · Accepted Answer

The second approximation of a silicon diode includes the ideal diode (a switch) in series with a fixed voltage drop, typically 0.7 V for silicon diodes, to represent the barrier potential.
