A diode and a 100- $\Omega$ resistor are connected in series with a 5.0-V power supply. The diode is connected so that it is forward-biased. The voltage drop across the resistor is
A) zero.
B) 0.60 V.
C) 4.4 V.
D) 5.0 V.

Question

Quizplus · Accepted Answer

When a diode is forward-biased, it typically has a voltage drop across it, often around 0.6 to 0.7 volts for a silicon diode. This means the rest of the voltage from the power supply (5.0 V - 0.6 V = 4.4 V) appears across the resistor.
