- noun the definition of whether an electrical signal is positive or negative, indicating whether a point is a source or collector of electrical current
- The property of having an excess or deficiency of electrons. An excess of electrons produces a negative polarity, and a deficiency of electrons produces a positive polarity. This determines the direction of the flow of current, as electrons move from a point with an excess of electrons towards a point where there is a deficiency of electrons. Also called polarity (2).
- The characteristic of having two opposite charges, positive and negative, within the same body or system. A battery, for instance, has two terminals, each with opposite polarity, which are the positive terminal and the negative terminal. Also called polarity (3).
