D) 9.3 V, 0.7 V

Quizplus · Accepted Answer

When a silicon diode is forward biased, it typically has a voltage drop of around 0.7 V. Therefore, the voltage across the diode is 0.7 V. 
The remaining voltage of the source (10 V - 0.7 V) is dropped across the resistor, which is 9.3 V. Therefore, the voltage across the resistor is 9.3 V. Thus, the correct answer is C.
