Hi guys... I'm new to the forum. I've got a lot of questions on electronics but for now i've got simple issues... I mean: all components work at specific voltages but it's hard to know what resistors and components to use. For example: a regular LED has max. voltage of about 2.0v. if you were to use a 6v power source we'll need a 330R resistor. Except that measuring what comes out of the resistor using that same battery doesn't get me a 4v voltage drop. How does that really work? How does one calculate the equivalent resistance/capacitance and make ohm's law calculations work for purposes of a real application?
Thanks in advance. Please feel free to bug me about machine language. i'm keen on it.
