Led Circuit Diagram And Working Principle Learn the basics of LED circuit diagrams and how to create a basic LED circuit with a few components. Follow the step-by-step guide and experiment with different resistor values to adjust the brightness of the LED.
Learn how to connect LEDs with different power sources and what type of current limiting resistor to use. See diagrams and details for 3V, 6V, 9V and 12V LED circuits.
Simple LED Circuit Diagram
I = LED current (we had been using 20 mA in our other calculations but since wiring LEDs in parallel draws more current I had to multiply the current that one LED draws by the total number of LEDs I was using. 20 mA x 2 = 40 mA, or .04A. And my values for the formula this time were: R = (9V - 1.7V) / .04A
Here is a diagram of the basic circuit. Just as before, the LED positive side is connected to the battery's positive side, and likewise negative to negative. The current will flow from the battery through the resistor and LED and then back to the battery. The resistor and LED are connected in series, which means one after the other.
