    A p-n junction in series with a resistance of\[5\,k\Omega \]is connected across a 50 V DC source. If the forward bias resistance of the junction is\[50\,\Omega ,\], the forward bias current is:

    A)  8.8 mA                

    B)         1 mA

    C)  2 mA                    

    D)         20 mA

    E)  9.9 mA

    Correct Answer: E

    Solution :

    Total resistance \[=50+5000=5050\text{ }\Omega \] \[\therefore \] Forward current \[i=\frac{50}{5050}\]                                 \[=\frac{1}{101}=9.9\,mA\]
