Question

Using the approximate equivalent model of a silicon diode and taking E=10 V and R=1k, what is the value of diode voltage at operating point?

(a) 0.7 V

(b) 0.3 V

(c) 10 V

(d) 9.3 V

This question was posed to me in class test.

I'd like to ask this question from Load Line Analysis in chapter Diode Circuit of Analog Circuits

Answer 1

Correct choice is (a) 0.7 V

Best explanation: In the approximate equivalent model, the diode voltage is fixed at the forward bias threshold voltage, which for a silicon diode is equal to 0.7 V
