The + and - you see on the end of batteries is the electrical polarity.
It refers to the direction of electron flow (more electrons at the -ve end, they flow to the +ve end through the circuit)
Electrical circuits need to be checked for polarity prior to energising. To ensure correct polarity it is necessary to ascertain that all single pole switching and protective devices are installed in the live conductor.
This ensures that when the said switch or protective device operates that the supply to the load which is being powered is interupted.
Reverse polarity would ensue if the switch was installed in the neutral as when operated the poad would cease to operate yet the load would still be energised.

What is the difference between s and p polarization in the context of light waves?
S and P polarization refer to the orientations of light waves. S polarization, also known as transverse electric (TE) polarization, has the electric field perpendicular to the plane of incidence. P polarization, also known as transverse magnetic (TM) polarization, has the electric field parallel to the plane of incidence. These orientations affect how light waves interact with surfaces and materials.
What is the difference between electrical polarisation and dielectric polarisation?
in electric polarization ion is formed which have more tendency to form then magnetic polarization . in magnetic polarization just transfer of electron via flux . so the basic reason is that ion has more mobility constant then electron.so electric polarization is more faster then magnetic polarization.
What are the differences between s polarization and p polarization in the context of light waves?
S polarization and p polarization refer to the orientations of electric fields in light waves. In s polarization, the electric field is perpendicular to the plane of incidence, while in p polarization, it is parallel to the plane of incidence. These orientations affect how light waves interact with surfaces and materials, leading to different behaviors such as reflection, refraction, and transmission.
What is the difference between p and s polarization in the context of light propagation?
In the context of light propagation, the difference between p and s polarization lies in the orientation of the electric field. P polarization has the electric field oscillating parallel to the plane of incidence, while s polarization has the electric field oscillating perpendicular to the plane of incidence. These orientations affect how light interacts with surfaces and materials.
What are the characteristics of TE and TM polarization and how do they differ in terms of their behavior in optical systems?
TE (Transverse Electric) and TM (Transverse Magnetic) polarizations are two types of light polarization in optical systems. TE polarization has an electric field that is perpendicular to the interface of the optical material, while TM polarization has a magnetic field that is perpendicular to the interface. In terms of their behavior in optical systems, TE polarization experiences total internal reflection at a critical angle, while TM polarization does not. Additionally, TE polarization has a higher reflectance at the interface compared to TM polarization.
What are the differences between circular and linear polarization?
Circular polarization and linear polarization are two different ways in which electromagnetic waves can oscillate. In linear polarization, the electric field of the wave oscillates in a straight line, while in circular polarization, the electric field rotates in a circular motion. This results in different orientations of the wave's electric field, which can affect how the wave interacts with materials and devices.

What is the IEEE definition for circular polarization?
Here is Wikipedias definition:In electrodynamics, circular polarization of an electromagnetic wave is a polarization where the tip of the electric field vector, at a fixed point in space, describes a circle as time progresses. If the wave is frozen in time the electric field vectors describe a helix along the direction of propagation. Circular polarization is a limiting case of the more general condition of elliptical polarization.
Why does the direction of polarization of light compare with the direction of vibration of the electrons that produced it?
The direction of polarization of light is related to the direction of vibration of the electrons that produced it because the oscillation of the electrons creates an oscillating electric field perpendicular to the direction of propagation of light. This electric field determines the orientation of the light wave's vibration, resulting in its polarization direction.
How is the direction of polarization related to the direction of the keyword?
The direction of polarization is related to the direction of the keyword through the alignment of the electric field vibrations. When the polarization direction matches the keyword direction, the keyword is more likely to be detected accurately.
What is the difference between s and p polarization in terms of their effects on light propagation?
S and P polarizations refer to the orientations of light waves as they propagate. S polarization, also known as transverse electric (TE) polarization, has the electric field perpendicular to the plane of incidence, while P polarization, also known as transverse magnetic (TM) polarization, has the electric field parallel to the plane of incidence. The main difference between the two is how they interact with surfaces and materials. S polarization is typically reflected more strongly at certain angles, while P polarization is more likely to be transmitted through surfaces. This difference in behavior can affect how light propagates through different mediums and surfaces.
What is polarization of an insulator?
Polarization of an insulator refers to the alignment of electric dipoles within the material in response to an external electric field. This alignment leads to the creation of a net electric dipole moment in the material, contributing to its dielectric properties. Insulators have a high resistance to the flow of electric current, making them valuable for electrical insulation purposes.
Does amplitude change in polarization?
The amplitude of an electromagnetic wave does not change with polarization. Polarization refers to the orientation of the electric field component of the wave, while amplitude refers to the strength or magnitude of the wave. Changing the polarization of a wave does not alter its amplitude.
