To determine the positive leg of a transistor, first identify its type: NPN or PNP. For an NPN transistor, the positive leg (collector) is typically the middle pin if it's in a standard TO-220 or TO-92 package, while the emitter is usually the outer pin. For PNP transistors, the configuration is similar, but the collector and emitter roles are reversed. Always refer to the specific datasheet for the transistor model to confirm pin configurations.
To determine the negative leg of a LED, you can look for the longer lead (anode), which is typically the positive leg, while the shorter lead (cathode) is the negative leg. Additionally, the flat edge on the LED's body usually indicates the cathode side, further confirming which leg is negative.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Anode and cathode. Anode = negative lead, cathode = positive lead.
A positive times a positive equals a positive, a negative times a negative equals a positive, a negative times a positive equals a negative(vice versa for the last one)
If your point is positive positive it is in 1. If tour point is negative positive it is in 2. If your point it negative negative it is in 3. And if your point it positive negative it is in 4.
The longest leg is the positive leg of any LED.
the negative leg is shorter than the positive leg.

A leg is a limb, it is neither positive or negative.
The longer leg of an LED is typically the positive (+) terminal, while the shorter leg is the negative (-) terminal. Additionally, the positive leg usually has a flat edge or a notch near it as a visual indicator.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Current flows from the anode (positive terminal) to the cathode (negative terminal) in a LED. The longer leg of the LED indicates the positive anode side, while the shorter leg represents the negative cathode side.
The longer leg on a LED light is called the anode. It is usually the positive terminal and is marked with a longer leg or a "+" symbol.
