Answer:
determine the cause of the static resistance of diode at 300°k
Given info : The current flowing through a p-n junction Si diode is 60mA for a forward bias of 0.9 v at 300K
To find : The static resistance and dynamic resistance of diode are ...
solution : static resistance = voltage/current flowing through p - n junction = V/I = 0.9v/60 mA
= 15 Ω
dynamic resistance for Si diode, r = 26η/I , where I is in mA
for Si , η = 2 and given I = 60
so, r = (26 × 2)/(60)
= 0.87Ω
Therefore static and dynamic resistances are 15Ω and 0.87 Ω respectively.
