P-N junction diode

Question

When a silicon PN junction is in forwad biased condition with series resistance , it has knee voltage of 0.6 V . Current flow in it is 5 mA , when PN junction is connected with 2.6 V battery , the value of series resistance is

Easy

A

$100 Ω$
B

$200 Ω$
C

$400 Ω$
D

$500 Ω$

Solution

$R = \frac{2.6 - 0.6}{5 \times 10^{- 3}} = 400 Ω$
