Nettet12. mar. 2016 · Let's say that one of the LEDs naturally draws a bit more current than the others at the common voltage. This means that, since power equals voltage times … NettetQ2. How much power will be dissipated in the LED? (Assume 2 V is dropped across the LED.) Answer: First we need to calculate the current through the 490 Ω resistor. Now we can calculate the power: 5/6 or 83% of the power is “wasted” in the resistor. Please link to us if you find the information helpful ... Visitor Counter rs3 blueberry bar

If you use an LED with high efficacy (200+ lumens/watt), less electrical energy is dissipated as heat. A decent LED will dissipate 70% of the electrical energy as radiant energy and 30% as heat.
