Using an LED LED wth DC (Direct Current)
LED wth AC (Alternating Current)
An LED (light emitting diode) requires about two volts to operate and twenty milliamps of current. A current limiting resistor must be used in series with an LED to prevent current over 20 mA from flowing; otherwise, your LED will be damaged. You may simply use Ohm’s law to calculate the resistor value. Here is an example, we have a circuit operating at 12 volts DC, and need to know the value of a resistor to use. The LED “wants” two volts to operate ; so subtract 2 from the 12 volts which is of course, ten. Plug the “ten” in at “E” and divide by “I” or .020 amps. The result is 500 ohms for the resistor value If you forget to subtract the two volts, the resistor value will be 600 and the LED will not be at maximum brightness. However, it will last much longer! (about double normal life). Another formula you can use is R=50(V-2). The R is for resistor, the V for voltage. We like this one as it is easy to recall and do in your head.
When using an LED with AC, a diode must be placed in series with the LED. Because AC will only be flowing 1/2 the time, we use a variation on the easy formula shown to the left(bottom). Use R=25(V2.7), which includes the voltage drop across the diode. So, if you have a circuit using 28 volts AC, multiply 25.3 (or 28V -2.7), times 25 equals 632 ohms. We need to use a standard value resistor, so use 680 ohms for “R”.

Using an LED LED wth DC (Direct Current)
LED wth AC (Alternating Current)
An LED (light emitting diode) requires about two volts to operate and twenty milliamps of current. A current limiting resistor must be used in series with an LED to prevent current over 20 mA from flowing; otherwise, your LED will be damaged. You may simply use Ohm’s law to calculate the resistor value. Here is an example, We have a circuit operating at 12 volts DC, and need to know the value of a resistor to use. The LED “wants” two volts to operate ; so subtract 2 from the 12 volts which is of course, ten. Plug the “ten” in at “E” and divide by “I” or .020 amps. The result is 500 ohms for the resistor value If you forget to subtract the two volts, the resistor value will be 600 and the LED will not be at maximum brightness. However, it will last much longer! (about double normal life). Another formula you can use is R=50(V-2). The R is for resistor, the V for voltage. We like this one as it is easy to recall and do in your head.
When using an LED with AC, a diode must be placed in series with the LED. Because AC will only be flowing 1/2 the time, we use a variation on the easy formula shown to the left(bottom). Use R=25(V2.7), which includes the voltage drop across the diode. So, if you have a circuit using 28 volts AC, multiply 25.3 (or 28V -2.7), times 25 equals 632 ohms. We need to use a standard value resistor, so use 680 ohms for “R”.
