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.

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 are the 2 ways to find out which is the positive leg and which is negative - led?
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
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>
What does E equals mc squared mean?
The simplest answer is: E is energy, m is mass, and c is the speed of light in a vacuum. But what does this really mean? Well, to be correct, Einstein's full equation is: E^2 = (mc^2)^2 + (pc)^2, where p stands for momentum. This equation applies to much more than the colloquial E = mc^2. It applies to moving objects, explains why mass drops when two atoms join together, and many other relativistic observations. Also, a very important point is that, because both sides of the equation are squared, solving for E (energy) yields to answers, a positive one and a negative one. This realization is what led to the hypothesis and eventually the discovery of anti-matter, which posses negative energy and/or mass.
How can you identify the different legs of a led?
The length of the legs. The positive leg is always longer than the negative one.
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.
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.
On a LED which leg is longer - positive or negative?
L.E.D has one leg longer then the other one, the longer one is positive and the smaller one is negative. If you have a l.e.d which has same length of legs then look inside the l.e.d for two kind of triangle peices and one of them will be smaller which is positive and one which is bigger and is negative.
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.
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).
How could you identify the negative leg of a LED if both legs were cut the same length?
Look at the size of the 'flags' inside the LED lens itself. The bigger one is the positive one. Don't ask me about a bi/tri colour LED, maybe with a capacitor.

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.

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