Hi, I am new to this form. I must be the dumbest father on this planet. I have read many, many books and working with electronic breadboards building and learning trying to teach my kid. The thing that is driving me crazy is what do ohms do to volts? See I know about ohms law, and I understand volts is really just pressure, it is current that flows. But what I just don't get is what’s with resistor numbers. I am trying to help my kid and I understand its concept.
Here is an easy example. If I have 9 volts and connect 3300k R to an LED, I see that the voltage dropped. But what I don't understand is what does the resistor mean by 3300k? Does it mean that that’s how many electrons it will let through regardless of volts?
Do you see what I am trying to get at? I don’t know why my mind is not latching on to the number system of resistor. What exactly does the 3300k do to volts to cause the drop. I know what resistors do but but I don't see what is ohms, is it a unit of measure.
Please help
