The symbol connected to the dot (usually the symbol found to the right) denotes the polarity of the center/tip, whereas the symbol connected to the broken circle denotes the polarity of the barrel/ring. When a device or adapter is described simply as having "positive polarity" or "negative polarity", this denotes the polarity of the center/tip.
Transformers are said to have "additive" or "subtractive" polarity based on their physical arrangement of terminals and the polarity of windings connected to the terminals. The convention used for North American transformers is that, facing the high voltage side of the transformer, the H1 terminal is on the observer's right.
A template for adding a electrical polarity symbol, indicating that a device requires a power supply with either a DC positive-center, DC negative-center, or alternating current (AC) ''barrel plug'' connector. Template parameters [Edit template data] Parameter Description Type Status Polarity polarity 1 The polarity of the coaxial power connector/''barrel plug'' connector that the device ...

A standard wall plug has polarity symbols on it. If used in a standard socket for that country you will be fine. But some sometimes you want to know the plus pole and the minus pole of your device without having to destroy the rubber around the wire to look at the electric wire colours.
Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.
As a simple example from the physics of magnetically confined plasmas, consider an axisymmetric system with circular, concentric magnetic flux surfaces of radius (a crude approximation to the magnetic field geometry in an early tokamak but topologically equivalent to any toroidal magnetic confinement system with nested flux surfaces) and denote the toroidal angle by and the poloidal angle by .
