I am testing the green LED of my RGB LED, and I am confused about its behavior on my DMM.
In the following picture, I connect the black lead to LED's cathode and the red lead to LED's anode, and get an open circuit reading. However, I was expecting something that tells the forward voltage.
In the following picture, I connect the red lead to LED's cathode and the black lead to LED's anode, and get 750mV reading. I was expecting an open circuit though. I wonder what the implications are from my DMM readings. Why 750mV? Thanks so much everyone!
