I think there's four. So do I calculate the impedance of them?
I don't know why it doesn't show vin, how can I figure out the base current without voltage or resistors to put into the fundamental equation to solve for Ic.
I really have no idea how to start this. All it says is find all the collector currents. This is my first course in opamps and I'm blown away. Thanks for your help sir.
It doesn't state how it is biased, which is why I added those base resistors. all I am given is Betas are 100 and Vbe is 0.7V. Connected to +-10V. It says that it is a LH 0005 National Semiconductor
Find all Collector currents
I don't even know where to start, I added base resistors but am still getting stuck how can I find current in the first transistor?
