1.7v = 8.4v2. Subtract the LED voltages from the supply voltage. e.g: 12v - 8.4v = 3.6v3. Divide the 3.6v (or your voltage) by the current through the string.for 25mA: 3.6/.025 =144 ohmsfor 20mA: 3.6/.02 = 180 ohmsfor 15mA: 3.6/.015 = 250 ohmsfor 10mA: 3.6/.01 = 360 ohmsThis is the value of the current-limiting resistor.Here is a set of strings for a supply voltage of 3v to 12v and a single.
