Question

A p-n junction is series with a resistance of $5 \mathrm{k} \Omega$ is connected across a 50 V DC source. If the forward bias resistance of junction is $50 \Omega$, the forward bias current is\ \

$\mathrm{R}=5 	imes 10^{3} \Omega . \overline{\mathrm{V}}=50 \mathrm{~V}$ $$ I=\frac{V}{R}=\frac{50}{\left(5 	imes 10^{3}+50ight)}=\frac{1}{100+1}=\frac{1}{101}=9.9 \mathrm{~mA} . $$
