Hi guys,
I am new to this forum and starting to play around with electronics.
I have a question about BC547 Transistors.
Using the following data sheet
http://www.futurlec.com/Transistors/BC547.shtml
Using a 9 V DC supply and the Emitter tied to ground and the collector having a RED LED and a resistor in series with Vcc.
Would I be able to turn the led off if I had a big enough Potentiometer? I have tried 100K pot and it dims it only not turning it completely off. So I am guessing the answer is yes.
My main question is what current do I need the base to be for the transistor to be open? And where does it indicate this on the data sheet.
