Assume an ideal diode has a series 10 k▲ resistor and is forward- biased with a 20 V source. The current in the diode is
A)2.0 mA
B)0 mA
C)1.0 mA
D)0.5 mA

Question

Quizplus · Accepted Answer

In an ideal diode when forward-biased, the voltage drop across the diode is negligible (assumed to be 0 V). Therefore, the entire 20 V is dropped across the 10 kΩ resistor. Using Ohm's Law (I = V/R), the current I = 20V / 10kΩ = 2 mA.
