DEFINITION OF ELECTRICAL POLARITY
Polarity Definition & Meaning - Merriam-Webster
The meaning of POLARITY is the quality or condition inherent in a body that exhibits opposite properties or powers in opposite parts or directions or that exhibits contrasted properties or powers in contrasted parts or directions : the condition of having poles. How to use polarity in
polarity | Definition & Examples | Britannica
Polarity, in chemical bonding, the distribution of electrical charge over the atoms joined by the bond. While bonds between identical atoms such as two of hydrogen are electrically uniform in that both hydrogen atoms are electrically neutral, bonds between atoms of different elements are electrically inequivalent.
Polarity - Wikipedia
Electrical polarity, positive or negative electrical potential; Magnetic polarity, north or south poles of a magnet; Polar reciprocation, a concept in geometry also known as polarity; Trilinear polarity, a concept in geometry of the triangle; Polarity, the direction of a wave's amplitude or its being in phase or antiphase
What is Polarity? - Definition & Example, Polar Vs Non
Jul 20, 2018Define Polarity “A state or a condition of an atom or a molecule having positive and also negative charges, especially in case of magnetic or an electrical poles.” Polarity, in general, refers to the physical properties of compounds such
Polarized Electrical Plug: Definition
Sep 17, 2020When referring to the two prongs on a plug, polarity simply means they have different functions based on the directional flow of the current. The wider prong connects the neutral wires (wires carrying unused electricity back to the breaker panel), and the narrow prong connects the hot wires (wires carrying electricity from the panel to an outlet or a switch).
What is polarity and why it's important for transformers
Mar 11, 2021Understanding polarity. Polarity is very important for the operation of transformers and protection equipment. A clear understanding of polarity is useful in understanding and analyzing transformer connections and operations as well as testing protection relays and systems.
Cohesion Definition and Examples in Chemistry
Jul 17, 2019It is caused by the cohesive attractive force between like molecules. Cohesion is an intrinsic property of a molecule, determined by its shape, structure, and electric charge distribution. When cohesive molecules approach each other, the electrical attraction between portions of each molecule holds them together.
What is Electric Charge? - Definition from WhatIs
What is electric charge? In physics, charge, also known as electric charge, electrical charge, or electrostatic charge and symbolized q, is a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge.
Power Supply: Definition, Functions - Electrical Academia
The polarity of the wave reverses at the frequency of the applied voltage. The output voltage of the transformer secondary also appears as a sine wave. The magnitude of the wave depends on the turns ratio of the transformer. The output is 180 degrees out of phase with the primary. The top of the transformer (point A) is joined to the diode anode.
Electrical Terms - SWTC
POLARITY - A collective term applied to the positive (+) and negative ( - ) ends of a magnet or electrical mechanism such as a coil or battery. POLE - One or two points of a magnet at which its magnetic attraction is concentrated.
