ETYM Cf. French polarité.
Having an indicated pole (as the distinction between positive and negative electric charges); SYN. sign.
In electricity, the quality of having two oppositely charged poles, one positive one negative.
The sign of the potential (voltage) difference between two points in a circuit. When a potential difference exists between two points, one point has a positive polarity and the other a negative polarity. Electrons flow from negative to positive; by convention, however, current is considered to flow from positive to negative. + prikaži više
