I have a wire with current I1 going thru it. As the voltage and I1 rise there is a transistor Q which turns on and it in turn stops the current from flowing. I1 and the voltage referenced is tied to the base of the transistor.
My question is:
When I1=.90amps Vbe = .63 volts
When I1=1.3 amps Vbe = .58 volts
When I1=1.5 amps Vbe=.38 volts
Why does the turn on voltage of the transistor keep dropping as the current increases?
(q1 is 2N3904)
Added picture upon request. Making it a bit more specific to my circuit
