The forward-bias voltage of a diode is changed from $0.6 V$ to $0.7 V$ , the current changes from $5 mA$ to $15 mA$ . What is the value of the forward bias resistance?

Answer:

10.00

Solution:

The forward biased resistance of a diode is

$R = \frac{∆ V}{∆ I} = \frac{0 .7 - 0 .6}{(15 - 5) \times 10^{- 3}}$

$R = \frac{0 .1}{10 \times 10^{- 3}} = 10 Ω$
