Question

What is polarity? Explain it in detail.

Answer 1

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.

Answer 2

Polarity is a term used in electricity, magnetism and electronic signaling. Suppose, there is a constant voltage also called an electric potential, b/w two objects or poles . in such a situation, one of the object or poles has more electron then the other . The pole with relatively more electrons, is said to have negative polarity; the other is assigned positive polarity. A magnetic field is characterized by north and south pole . Magnetic polarity is refer to the orientation of these poles in space.
