NettetA typical indicator LED requires a forward current of about 15 mA to light up and produces a forward volt drop of about 2V (depending on the LED type). We can use a simple formula to estimate the resistor value required: Resistor value = (Vs – 2) / 15 × 10−3. So if the supply is 5V, the resistor value required is 200 Ω. Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical. powderhorn ski resort weather cam
