Heh Guys, Please refer to the attached schematic for this question. Will the circuit work as drawn or do I need a series resistor for each LED? Please note that the LEDs are of the high intensity type (4 volts and 20 mAmps each) and all are on at the same time. Anyway using ohm's law I calculated a resistance value of 12.5 ohms (rounded up to 20). In addition the LEDs should shine for 2 hours (battery at 800 mAmp hours). Please reply and merry Christmas to all.
