Hey again. I have a circuit that I've made and I was told I should put resistors in so that I don't blow out my transistors and buttons. Ok, I can do that... but I have no idea what size of resistor I need! Picture:(adsbygoogle = window.adsbygoogle || []).push({});

I'm using TIP41C Transistors:

Information Sheet

I think what I needed from this sheet was the "Continuous base current" of 3A?

12V = 3A * R

R = 4ohm?

Does that sound right? Am I oversimplifying it?
