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 Closest Standard 5% Resistor= ...
LED Resistor Calculator To calculate the resistor needed for a simple LED circuit, simply take the voltage drop away from the source voltage then apply Ohm's Law. In other words... where: VSis the source voltage, measured in volts (V), ...
Our LED calculator will help you determine the value of the current limiting series resistor when driving a single or an array of low-current LEDs. To get started, input the required values and hit the “Calculate” button. The program will draw a small schematic, display the calculated resis...
Every (LED) light emitting diode has a current that they can handle safely. Going beyond it maximum current will damage the LED. So limiting the current through the LED with the use of a series resistor is a common practice. LED resistance calculator will help you determine the value of th...
LED resistance calculator use to determine the series resistor needed to connect various series combinations of light emitting diodes or "LEDs". LED resistance calculator will assist you pick the resistors make the connections for any number of LEDs. ...
This calculator will show you what sized resistor to use for a series of LEDs. Enter any voltage between 1 and 150 in the first column. Enter the LED voltage drop (LED voltage) in the second column. This can range from 1 to 100. Enter the LED current in the third column. This ...
