A silicon diode is forward-biased. You measure the voltage to ground from the anode at ________, and the voltage from the cathode to ground at ________.
A:
0 V, 0.3 V
B:
2.3 V, 1.6 V
C:
1.6 V, 2.3 V
D:
0.3 V, 0 V
Answer:B
For silicon diodes, the built-in potential is approximately 0.7 V. Thus, if an external current is passed through the diode, about 0.7 V will be developed across the diode such that the P-doped region is positive with respect to the N-doped region and the diode is said to be "turned on" as it has a forward bias.
Therefore, 2.3 V - 1.6 V = 0.7 V. Hence the answer is correct.
