The question given is to solve for the collector current. The emitter is floating and the collector is biased at 5V with respect to the base.
The givens are Is = 10fA, BF = 100, and BR = 1
I understand the problem, I am just having trouble figuring out how to set it up properly. My assumptions are that iE = 0, so therefore Vce = 0
using the equation
ic = Is*e^((VBE/VT)(1+ VCE/VA))
Then VBE would be 5V, VT = 0.025, and VCE = 0?
Since iE is equal to zero then I know that iE = (BF +1)iB = 0, so then iB = 0 which does not make sense because ic = BF*iB and ic is what we are solving for.
Any help would be appreciated. Thanks in advance.
