Question

Quizplus · Accepted Answer

The forward voltage drop across a silicon diode typically is around 0.7 V (or 700 mV) when conducting. Additionally, the voltage drop across the bulk resistance (12 Ω) due to the forward current (7 mA) can be calculated using Ohm's law (V = IR), which gives 12 Ω * 7 mA = 84 mV. Therefore, the total forward voltage drop is approximately 700 mV + 84 mV = 784 mV.
