Hey,
I have been learning about basic electronics for a few weeks (again) and currently i'l working with transistors. I created a very basic circuit in a simulator and got the exact expected result (photo below). I then went ahead and bread boarded the circuit and didn't get what I was expecting. I was wonder if someone could look at it for me?
Simulated Circuit
I get the pretty much the expected result.... 1.5mA into Base and 115mA on the LED
Bread Board Circuit
This I do not get what I see on the simulated circiut.... I get 1.7mA in the Base (i'm fine with this).... but I only get 3.8mA to the LED
Can anyone explain why this happens? do I have something wrong?
Parts
- 2x 1.2v AA Battery
- 1K resistor
- PN2222A Tranisitor
- Red LED
Thanks,
--James
