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: 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?
