23 Ιαν 2024 · Our user-friendly calculator helps you determine the resistance needed to power one or more series-connected LEDs from a specified voltage source at a designated current level. The calculation, rooted in Ohm's Law, also accounts for the voltage drop across the LED.
The calculator on this page allows you to calculate the size/value/resistance of current-limiting resistor required to run an LED at the correct current for that type.
5 Οκτ 2024 · Use this calculator to determine the appropriate resistor value for your LED circuit. Enter the supply voltage, forward voltage, and forward current to calculate the recommended series resistor.
Use this tool to calculate the resistance required to drive one or more series-connected LEDs from a voltage source at a specified current level.
When calculating the resistor size that you need to use, you need to find your source voltage, the forward voltage of the LED (basically, at which point the LED starts conducting), and then how much current you want it to conduct.
25 Μαΐ 2021 · Use this calculator to find out the ohm value and tolerance based on resistor color codes.
Find the resistor value and power required to connect multiple LEDs with our LED Series Resistor calculator using supply and forward voltage.
