When the forward bias voltage of a diode is changed from $0.6 V$ to $0.7 V$ , the current changes from $5 mA$ to $15 mA$ . Then its forward bias resistance is

Answer:

10.00

Solution:

Forward biased resistance = $\frac{∆ V}{∆ I} = \frac{0.7 - 0.6}{(15 - 5) \times 10^{- 3}}$

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