The Formula. R = (Supply voltage - LEd forward voltage)/LED current. = (3.7 - 3.3)/100 = 0.4/0.1 = 4 ohms. The required wattage would be 0.4 x 0.1 = 0.04W, so a 1/4 watt resistor would be more than enough. Assuming the cell to be rated at 800mAH, with 5 LEDs, the approximate back up time available from the cell could be calculated using the.
