Here is just a basic question that it really isn't covered in the stuff I am reading.
When your designing circuits, basic or complex, we should always design it by using Ohms law right. We also use ohms law in detemining individual components information, such as voltage etc.
But how do the 2 relate?
For example suppose you have a basic circuit with more than one component such as 2 LEDs and a current limiting resister. You have a basic power supply of 10 volts. Each LED takes volts 20 mA. From this I determine that I need a 200 ohm resister. But from my 2 LEDs I determine that each one has a resistance value of 100 ohm. So my circuit has a total resistance value of 400 ohms. Is that correct? More questions will follow if I can determine that this is correct.
Thanks for any help. This problem has been bugging me for a while.
