Green led resistor calculator
WebThe first thing that we need to calculate is the voltage “Vr” across the resistor. To do this, line up your forward voltage (Vf = 2 V) directly beneath your system voltage, Vcc = 9 V. (If you’ve already done this calculation in your head, … WebThe ballast resistor can be calculated using the formula: R = V −V LED I = 12−2 0.03 = 333Ω R = V − V L E D I = 12 − 2 0.03 = 333 Ω The resistor must have a resistance of 333 Ω. If the precise value is not available, choose the next higher resistance value to keep the current below the LED limits. Multiple LEDs in a Series Circuit
