A p-n junction diode is reverse biased with a voltage of \(8 \mathrm{~V}\). If the resistance of the diode is \(4 \times 10^7 \Omega\), then the reverse saturation current is
- A \(32 \mu \mathrm{A}\)
- B \(2 \mu \mathrm{A}\)
- C \(0.2 \mu \mathrm{A}\)
- D \(0.5 \mu \mathrm{A}\)
Answer & Solution
Correct Answer
(C) \(0.2 \mu \mathrm{A}\)
Step-by-step Solution
Detailed explanation
Saturation current \[ \begin{aligned} & \mathrm{I}=\frac{\mathrm{v}(\text { reverse biased voltage })}{\text { diode resistance }} \\ & =\frac{8}{4 \times 10^7}=0.2 \mu \mathrm{A} \end{aligned} \]
