Resistor Calculator If you don't have a calculator handy, use this JavaScript resistor calculator to do the math. Source Voltage= LED Forward Voltage Drop= LED Forward Current in Milliamps= Needed Resistance in Ohms= Using Closest Standard 5% Resistor ...
LED Resistor Calculator All LEDs require some form ofcurrent limiting. Connecting an LED directly to the power supply will burn it out in a heartbeat. Overdriving, even briefly, will significantly reduce it’s life and light output. Fortunately, driving a single or a string of low current (...
Working of LED Resistor CalculatorEvery LED has its own characteristics and specifications, depending on the materials used to make them, their colour and many other parameters. As we know the LEDs have a forward voltage, just like any other diode. To turn them on we need to supply the ...

- Solder the wire leads of the LED's into their correct holes on the driver. If single Color LEDs are being used: - Its usually best if each LED gets its own resistor, but otherwise a single larger resistor could be used.This Calculatorcan be used to calculate resistor values orContact...
For parallel LED circuits, use the series calculator above, but enter only a single row of LEDs. The results will be the same for every parallel row in your circuit. For example, if you want to use 36 LEDs rated at 2.7 volts, and a 12 volt power supply, you would enter only 4 LED...
Check out this in-depth guide to choosing the correct power supply or refer to our power supply calculator chart for a detailed look on which power supply you need. To calculate the size of the power supply for your LED strip light, you need to calculate the total watts used in your ...
