Question

In a Silicon p-n junction diode, for 20 V forward voltage, the forward current produced is 10 mA. Calculate its forward resistance. 
 

Hint:

Forward resistance is calculated by dividing the forward voltage by the forward current.

Answer 1

The forward resistance (\( R_{\text{forward}} \)) is given by Ohm's law: \[ R_{\text{forward}} = \frac{V}{I}, \] where \( V = 20 \, \text{V} \) and \( I = 10 \, \text{mA} = 10 \times 10^{-3} \, \text{A} \). Substituting the values: \[ R_{\text{forward}} = \frac{20}{10 \times 10^{-3}} = 2000 \, \Omega. \] Thus, the forward resistance is \( 2000 \, \Omega \).
