Hai I am a beginner hobbyist tried to do transistors configuration but i met some questions i really don't understand
I have attached two pictures that i did for my transistor configuration but are that possible with that case
a) the NPN Transistor, I don't have to bias the Base and I can turn on the LED
b) PNP Transistor, I don't need the collector connection, I can turn on the LED
Can everyone explain to me why these could happen???
Isn't that those transistors are malfunction? I had tried a whole batch of the Transistors (NPN & PNP) but all showed the same result
