- Electricity.
- the deposit of gases, produced during electrolysis, on the electrodes of a cell, increasing the resistance of the cell.
- a vector quantity indicating the electric dipole moment per unit of volume of a dielectric.

polarization
/ ˌpəʊləraɪˈzeɪʃən /
noun
- the condition of having or giving polarity
- physics the process or phenomenon in which the waves of light or other electromagnetic radiation are restricted to certain directions of vibration, usually specified in terms of the electric field vector
polarization
/ pō′lər-ĭ-zā′shən /
- A condition in which transverse waves vibrate consistently in a single plane, or along a circle or ellipse. Electromagnetic radiation such as light is composed of transverse waves and can be polarized. Certain kinds of light filters, including sunglasses that reduce glare, work by filtering out light that is polarized in one direction.
- The displacement of positive and negative electric charge to opposite ends of a nuclear, atomic, molecular, or chemical system, especially by subjection to an electric field. Atoms and molecules have some inherent polarization.
- An increased resistance to the flow of current in a voltaic cell, caused by chemical reactions at the electrodes. Polarization results in a reduction of the electric potential across the voltaic cell.
polarization
2- In politics, the grouping of opinions around two extremes: “As the debate continued, the union members were polarized into warring factions .”
