How to Make a Very Simple NPN Transistor Tester

in this instructable i will show you how to make a very simple NPN transistor tester.
You Will Need:

a NPN transistor (to test)
a 10K OHM resistor
a 470 OHM resistor
a LED
a on/off switch
and a 9V battery (5-12V)
a 10K OHM resistor
a 470 OHM resistor
a LED
a on/off switch
and a 9V battery (5-12V)
Making It.


here are the schematics. and a picture of my finished product.
