Hello guys can anybody tell me whats the meaning of "The Occurance Of Ac Voltage , And When Ac Disrupt Occur " ?

It certainly DOES MATTER which way you hook it up. Connect the lower line on the diagram to the "active" wire of an AC outlet and you are directly connected to 120v or 240v.
That's why you should not give advice unless you have actually tested what you provide.
I think it a little less then 1.44 W. more like 422.5 Milliwatts but any way I let it stay on for a hour with just a half watter 10 k and it didn't get hot
You no phone's have them Optocouplers in them to pickup the ring-signal AC wave it can be up too 90 volts
And I thought blueroom meant he stuck a coathanger in a light socket.
and DETECTED AC volts!!
I had a boy that worked forcoathanger in a light socket
It's 120 volts Ac I showed you the plug and the led lit. Your getting about 65 volts if the line is 60hz I'm not going to play with 120 volts DC . Any way I checked it with vom It's
422.5 Milliwatts
Forward makes sense. And after all it IS a diode and is blocking the current on one direction and doesn't have to work too hard at it since the reverse leakage current is probably enough that the resistor is soaking up / limiting the effective reverse voltage to a possibly tolerable level. Resistor only takes a beating - er a - heating at 50% duty cycle and at a halfasine duration only.
Just remember that this non-linear relationship between voltage and current means that Ohm's Law doesn't work for LEDs.
