Just trying to get an LED to light up on my breadboard (I am out of practice). Have built this circuit as pictured below (yes, a lot more wires than necessary). LED polarity is understood, and the small side (cathode) is connected to negative, and the larger sider (anode) is connect to positive.
The resistor is brand new 330Ohm pulled from a pack of others.
Power Supply is set to 9V and is showing 20mA.
Swapping the resistor, LED, and LED polarity changes nothing...
Did some simple ohms law math and probed with a multimeter to check expected values...all good.
What is wrong here?
