Hello
I understand bipolar transistors (NPN and PNP) are reliant on current. With PNP I belive current flows out or away from the base and the rule is if the base is positively charged then its as if the switch is open and if grounded then it is as if its closed.
So I put a 12v led after the transistor from the collector and my supply voltage of 9v in the emitter of the transistor. I grounded the base of the transistor and when i put my meter on the base to test the volts there the transistor gave out a spark and got fried.
Why is it this happened, diagram too explain below
I a'm an ametur at electronics and learning lots from this forum (my first time playing with transistors)
Thank you for your replies.
