What is the normal convention(safe and reliable), should one connect NPN transistor base to ground or should a resistor be used?
My logic tells me that in common emitter mode, shorting base to ground turns off transistor so no current flows between emitter and collector and also base current must be zero. If current is zero there is no need for resistor?
At the same time I think there should be some minor base capacitance that will discharge when base is shorted and thus could exceed rated base current? (However I cant see base capacitance mentioned in BC817 datasheet)
