Capacitors block DC voltage, but pass AC voltage.dirtybogner wrote: ↑18 Jul 2020, 11:08 Why is it not good if the output were shorted? I think the output after 2.2uF cap has no voltage. Is it for jfet behavior?
Sorry if this is basic question.
So, if there is a signal at the input and the output is shorted, it can potentially damage the transistor. So, the resistor is present to limit AC current.
