Hi,
In the active mode of the transistor, this results in an inverse phase between the input signal and the output signal voltages. I think the currents Ib and Ic would fluctuate in phase with the fluctuations of the voltages in their respective circuit loops. This would mean that when Ib is high, Ic will be low. If this is correct, then the relationship Ic=hfe*Ib does not seam to give a snapshot info of what is happening. That is to say, If I freeze the circuit at any particular time and take readings of Ic and Ib, won't I find that when Ib is up then Ic is down?
Please help.
Thanks!
I didn't find the right solution from the Internet.
