Reliving my circuit days and came across something I forgot
Say you had a massive nearly infinite current source. Maybe its a giant battery or similar.
You can this giant battery to the base of a simple npn but with no base resistor.
You connect the emitter with say a 500 ohm resistor to ground.
With no base resistor how do you determine what the base current is? AKA what is the base terminal input impedance?
Trying to understand what would dictate how much base current can be sunk if there is no base resistor to limit it.
Thanks
