Below is the following circuit. It is an npn BJT in forward active mode.
R2 = 8k ohm
R1 = 1.4k ohm
Rc = 5k ohm
Re = 1k ohm
Vb = 1.512V
Ve = 0.876V
Vc = 5.512V
These voltages are actual values measured in the lab. Im trying to find ib, ic, and ie, all terminal currents.
This is what I did:
Ie = Ve/Re = 0.876mA
Ic = (10-Vc)/Rc = 0.8976mA
Ib = Ie - Ic = -21 micro A
How does this make any sense???
I need to find the terminal currents and find the gain, beta. Are the terminal currents different from the currents through the resistors?
I feel like I am doing something very wrong here, please help!
