Enter the R1 and R2 resistor values in the below LM317 calculator to calculate the output voltage, OR you can enter the target output voltage and R1 and can calculate the required value of R2 resistor. Resistance 1 (R1) Resistance 2 (R2) Output Voltage (Vout): Volt How LM317 ...
This easy-to-use calculator instantly tells you the proper size resistor to use for your particular LED's characteristics and your power supply voltage. Choosing the correct value of the resistor is essential to proper operation of the LED.
This calculator will show you what sized resistor to use for a single LED. Enter any voltage between 1 and 250 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 can be...
Use this LED resistor calculator to find out the suitable resistance for your LED circuit consisting of one or more LEDs.Inputs Source Voltage (Vs): Volt LED Forward Voltage (Vf): Volt (Typical value: 2v) LED Forward Current (If) Milliamps (Typical value: 20mA) No. of LEDs in Series...
This calculator is based on theOhms Law Calculator, but takes into consideration the voltage drop from the LED. To use the calculator, enter any three known values and press "Calculate" to solve for the others. Voltage Source (VS)
The voltage divider Resistor calculator calculates the value of the resistor, R2, of the voltage divider network based on the value of resistor, R1, the input voltage, VIN, and the output voltage, VOUT. This resistor value of R2, is calculated by the formula, R2= (VOUT * R1)/(VIN - ...
from the resistors surrounding the op-amp, and the inherent voltage and current noise specs of the op-amp itself. If you leave out the op-amp datasheet specs, the calculator uses an ideal, noiseless op-amp. You can also leave out R2 and the pot values, if you will not use these ...
In order to calculate the resistance and power dissipation, you need to input a few parameters into this LED resistor calculator: Circuit type. Are your LEDs connected in series or parallel? n– number of connected LEDs. V– supply voltage of your circuit. Typical values are 5, 7, and 12...
