Question

The current through an ideal PN-junction, shown in the following circuit diagram, will be,

• A. Zero
• B. $1\text{mA}$
• C. $10\text{mA}$
• D. $30\text{mA}$

Answer 1

The correct option is A Zero

The diode is reverse biased, so, drawing the equivalent circuit,


Now, $I=\frac{2-1}{100+Rv}=\frac{1}{100+Rv}\text{A}$

but $Rv$ is very high

$\Rightarrow I\approx 0$

Hence, $\left(A\right)$ is the correct answer.
