The V-I characteristic of a silicon diode is shown in the Fig. 14.17. Calculate the resistance of the diode at (a)I_(D) = 15 mA and (b) V_(B)=-10 V |

Answer» Solution :Considering the diode characteristics as a straight line between I = 10 mA to I = 20 mA passing through the origin, we can CALCULATE the resistance using OHM’s LAW. (a) From the CURVE, at I = 20mA, V= 0.8 V, I= 10mA, V= 0.7 V `r_(fb) = DeltaV//DeltaI = 0.1V //10 mA = 10 Omega` (b) From the curve at `V = -10 V, I=-1 MUA`, |
