Nettet29. jun. 2024 · Resistance = (Power supply voltage - LED voltage drop)/led current. Once you know those values you can see how many watts your resistor will dissipate. Check out wikipedia on leds R= (8-3.5)/.8=5.625 ohms P=IV=.8*4.5=3.6 Watts It is possible I am misunderstanding your specs, or that they are wrong. NettetSingle LEDs. When computing the value of a current limiting resistor for a single LED, the basic form of Ohm's Law — V = IR — becomes: where: V batt is the voltage across the resistor and the LED. V led is the forward voltage of the LED. I led is the forward current of the LED. Figure 1 (a) shows an example of a single LED circuit. NettetOur first calculation above shows that to limit the current flowing through the LED to 10mA exactly, we would require a 300Ω resistor. In the E12 series of resistors there is no 300Ω resistor so we would need to choose the next highest value, which is 330Ω . gsw hot water heater age
