Question

From the given circuit diagram, what is the voltage across diode?

(a) 10 V

(b) 5 V

(c) 0.7 V

(d) 0 V

I got this question in final exam.

I'd like to ask this question from Diode Approximations and Series Connection in portion Diode Circuit of Analog Circuits

Answer 1

Right choice is (a) 10 V

Best explanation: As the diode is reverse biased, the current in the circuit is zero and hence the voltage across the diode is equal to the source voltage = 10 V.
