Using an LED
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 flow
ing; 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(V2). The R is for resistor, the V for voltage. We like this one
as it is easy to recall and do in your head.
LED wth DC
(Direct Current)
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 volt
age 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”.
