Procedure to getting Voltage and current of an LED without knowing ANYTHING else?
So I need to know if there is a procedure to finding out the current and voltage of an led and that is without knowing a single rating about it. It it guesswork or is there a proper testing procedure? It can be a 1,5v can be a 2.5 or a 3v led I don't know. What should be tested first, what should be second?
All I have is a basic multi-meter and besides checking batteries voltage I have't been using it for anything else.
Thank you, folks.
