Homework Statement
Find the change in diode voltage if the current changes from 0.1 mA to 10 mA. Ans. 120 mV
Homework Equations
V2-V1=VTln(I1/I2)
The Attempt at a Solution
That is all the information given. The only equation I can think to use is the diode voltage/current relationship, but a value for initial voltage is not given. The calculation assuming V1=0.7 V V2=0.025ln(10/0.1)+0.7 = 0.8151.
Thanks for the help.
