Hi all,
I've got some LEDs that I've been advised to measure the Forward Voltage on as the Spec sheet gave a wide variance (1.8-2.4).
Using an online calculator I worked out that I would need a 560ohm resistor for a single LED from a 12v source. I've put in the calculator 20mA as the current.
So my question is, what figures should I expect to see from the mulit meter when I measure before and after the LED and Resistor?
Thanks,
Ant
