If the line touching the tip in the centre has a + (plus) symbol, this means the tip is positive, and the outer shell is negative. The number of prongs doesn't matter. It is far from true in the case of laptops and comparable devices (Arduino's, Raspberry Pis etc) where the pin (centre) is positive. For example, when a plug is not inserted correctly, energizing the wrong prong can cause a short circuit or even an electrical fire. 4 How do you tell if a wire is hot or neutral? Is the big side of a plug positive or negative? Firstly, a loose connection could be the cause. To prevent that from happening, the receptacles are polarized, which means that the neutral prong is wider than the hot prong.
