what does polarity mean
Part of the Smart grid glossary: Also see bipolar signaling and unipolar signaling. Polarity is a term used in electricity, magnetism, and electronic signaling. Suppose there is a constant voltage, also called an electric potential or electromotive force (EMF), between two objects or points.In such a situation, one of the objects or points (poles) has more electrons than the other.art of the Smart grid glossary: Also see bipolar signaling and unipolar signaling.
