The answer will depend on the context in which the legs are defined. Since no information on that is provided, it is not possible to give a more helpful answer.
when work is positive and when playing is negative
Yes Work can be positive or Negative.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
what is positive and negative
Anode and cathode. Anode = negative lead, cathode = positive lead.
A leg is a limb, it is neither positive or negative.
the negative leg is shorter than the positive leg.
when work is positive and when playing is negative
because the negative leg is shorter.
Yes Work can be positive or Negative.
No, this will not work. Postitive to Negative/Negative to Positive will work.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
what is positive and negative
Anode and cathode. Anode = negative lead, cathode = positive lead.
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.
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.
Positive.
