Led Diode Wiring Diagram. The cathode is marked on the rim of the led body with a flat area shown in the diagram. This led calculator will help you design your led array and choose the best current limiting resistors values.
As per the datasheet of the 5mm white led the forward voltage of the led is 3 6v and the forward current of the led is 30ma. A light emitting diode or led lights up when electrically biased in the forward direction. This led calculator will help you design your led array and choose the best current limiting resistors values.
Therefore v s 12v v led 3 6v and i led 30ma.
On the physical led the longer lead or leg of the led is the anode. Otherwise the structure will not work as it ought to be. Four circuits with description. The cathode is marked on the rim of the led body with a flat area shown in the diagram.
