On an LED, one leg will be shorter than the other.
The shorter leg is the negative polarity.

0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
What do negative and positive legs of led mean?
The LED will only emit light when its wires are connected to the battery in the correct direction. When it's flipped, it doesn't shine. The designations of its "legs" ... or wires, or terminals, or leads ... tells you which side of the battery each one must connect to, if you want it to shine.
What is the golden ratio according to Gottman?
It looks like this question may be filed in the wrong spot. While it includes a "golden ratio," and therefore looks like a math question, it is really about relationships. John Gottman is a researcher and expert in relationships, particularly marriage. In studying couples, Gottman began to recognize and quantify symptoms that led to marital distress and eventual divorce. In that process, he also identified the opposite: how can marriages be improved and saved? And herein lies the "Golden Ratio." The ratio is of positive interactions to negative interactions. Or in mathematical formula (Positive interaction)/(Negative interaction). Dr. Gottman determined that for every negative interaction, there are five positive interactions in healthy couples (or couples that want to move toward health). The beauty of this ratio is that it demonstrates 1) that healthy couples are not without painful moments, and 2) you can do something to improve a distressed relationship, simply by focusing on more positive interactions. So the short answer is 5/1 positive to negative interactions. Lee H. Baucom, Ph.D. Creator, <a href="http://savethemarriage.com">Save The Marriage System</a>

0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
How can you identify a negative leg on a LED?
the negative leg is shorter than the positive leg.
What is the short and long legs of LED called?
Cathode (negative) is the shortest leg and there is a flat edge on the base of the LED, and it must be connected to the negative wire or "-" connection. Anode (positive) is the longest leg, and must be connected to the positive wire or "+" connection, as electricity will only pass through a LED from positive to negative.
How can you identify a cathode nigative to an LED?
LED has two pins,one is anode(positive) and the other is cathode(negative).The smaller pin is cathode(negative) and the longer pin is anode(positive).

LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
In a battery using device the current would flow from the Negitive end through say a led light then find its way to the Positive end of the battery completing the transition?
NO. By tradition and usage : current flows from positive to negative. In reality : electrons flow from negative to positive.
Why are led legs different in size?
Current will only flow one way through an LED, so it has a positive leg and a negative leg. One of them is longer to signify which is which (longer is negative). The negative side also has a chamfered edge on the LED itself.
How do you tell the difference between positive and negative on a led?
The longer wire is the positive end, but if the wires are the same length, check inside the LED. There are two easily seen parts connected by a wire, the smaller is the positive.
Do LED's have polarity?
Yes they do - it means the long stem is positive and must be connected to positive wires and the short stem to negative wires
How does religion impact society in a positive or negative way?
There are several positive and negative aspects. For example:* Positive: religions often serve as a moral guide, and as inspiration for moral and ethics. * Negative: religious fanaticism has led people to commit all sorts of crimes in the name of religion.
In what two ways can you tell the polarity of and LED light?
If you plug it it in, if it doesn't light it's the wrong way round. Although these other two are more 'conventional': -The negative wire is closest to a small flat 'spot' on the LED's base. -The longer leg is the positive wire
How does an LED light not light up when a positive wire is on a negative terminal and negative wire on positive terminal?
Because LED means light-emitting diode and the clue is in the diode, because diodes are 'polarised', which means that the current must flow in the correct direction for them to operate correctly.
