Hi. I am new to transistors and I think I have figured out what I am doing, but I would like to confirm that I have the right resistor values for a emitter follower circuit. I wanted 100mA output, but the closest 5 watt resistor I have is 68R. (If I figured correctly, the resistor will need to be over 1 watt) So I am working around that with what I think will be 117mA output. The NPN transistor is a MPS2222A.
Attached is a schematic of the circuit.
With the voltage divider bias resistors, the closest values I have are 680R and 880R.
So I have two questions. 1. Have I done the math correctly for figuring out the resistor values? 2. Are the 680R and 880R resistors close enough to work?
Thanks
Scott
