Hello.
In enclosed file there's a BJT with a sine signal on base, through simply a capacitor.
I don't understand the reason why if I put no resistor from base to ground, I can't saturate the BJT, whereas I get it saturated if I put the resistor.
Why the BJT conduct better with the resistor from base to ground?
It seems that the base current is higher, but I don't understand physically why.
Thank you for any kind explanation.
Regards
