Question

What is the current through an ideal pn - junction diode shown in figure below?

• A. Zero
• B. 10 mA
• C. 20 mA
• D. 50 mA

Answer 1

Answer: (C)

20 mA

Answer 2

The potential of $p$-side is more positive than that of $n$-side, hence, diode is in forward biasing. in forward biasing current flow is possible and $I=\frac{V}{R}$ $=\frac{(3-1)}{100}$ $=20\, mA$ .
