Question

From the given circuit diagram, what is the value of voltage across R2?

(a) 9.324 V

(b) 5.3 V

(c) 0 V

(d) 5.8125 V

This question was addressed to me in my homework.

Question is from Diode Approximations and Series Connection topic in portion Diode Circuit of Analog Circuits

Answer 1

Correct answer is (d) 5.8125 V

The explanation is: Here, current I=10-0.7/4k=2.325 mA

Here, VR2 = I x R2 = 5.8125 V.
