For the forward biased diode characteristics shown in the figure,...

For the forward biased diode characteristics shown in the figure, the dynamic resistance at ${I}_{D} = 3mA$ will be ________ $Ω .$

For the forward biased diode characteristics shown in the figure, the dynamic resistance at I _ D = 3mA will be

Correct answer

0

Step-by-step solution

${R}_{d} = \dfrac{dV}{di} = \dfrac{1}{\left(\dfrac{di}{dv}\right)} = \dfrac{1}{\left(\dfrac{5 - 1 \times {10}^{- 3}}{0 . 75 - 0 . 65}\right)}$

$\dfrac{100}{4} = 25Ω$
