Question

For the forward biased diode characteristics shown in the figure, the dynamic resistance at $I_D=3 \mathrm{~mA}$ will be

Professor PC Thomas Classes · Answer

(a) : From the diagram the dynamic resistance will be\ $ R_d=\frac{\Delta V}{\Delta i}=\frac{0.75-0.7}{(5-3) 	imes 10^{-3}}=25 \Omega $
