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

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

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

Options

  1. A25
  2. B75
  3. C125
  4. D175

Correct answer

A. 25

Step-by-step solution

Rd=dVdi=1(didv)=1(5−1×10−30.75−0.65){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)}

1004=25Ω\dfrac{100}{4} = 25Ω
