Polarization Solution

Follow our step by step solution on how to calculate Polarization?

FIRST Step Consider the formula

P = Χ e \cdot [Permitivity-vacuum] \cdot E

Next Step Substitute values of Variables

∴

P = 800 \cdot [Permitivity-vacuum] \cdot 300V/m

Next Step Substitute values of Constants

∴

P = 800 \cdot 8.9E-12F/m \cdot 300V/m

Next Step Prepare to Evaluate

∴

P = 800 \cdot 8.9E-12 \cdot 300

Next Step Evaluate

∴

P = 2.124E-06C*m²/V

Next Step Convert to Output's Unit

∴

P = 0.02124C*cm²/V

LAST Step Rounding Answer

∴

P = 0.0212C*cm²/V

How to Evaluate Polarization?

Polarization evaluator uses Polarization = Electric Susceptibility*[Permitivity-vacuum]*Electric Field Strength to evaluate the Polarization, Polarization describes the orientation of the electric field vector of an electromagnetic wave, which can be linear, circular, or elliptical, determining the wave's propagation characteristics. Polarization is denoted by P symbol.

How to evaluate Polarization using this online evaluator? To use this online evaluator for Polarization, enter Electric Susceptibility (Χ_e) & Electric Field Strength (E) and hit the calculate button.

FAQs on Polarization

What is the formula to find Polarization?

The formula of Polarization is expressed as Polarization = Electric Susceptibility*[Permitivity-vacuum]*Electric Field Strength. Here is an example- 212.4 = 800*[Permitivity-vacuum]*300.

How to calculate Polarization?

With Electric Susceptibility (Χ_e) & Electric Field Strength (E) we can find Polarization using the formula - Polarization = Electric Susceptibility*[Permitivity-vacuum]*Electric Field Strength. This formula also uses Permittivity of vacuum constant(s).

Can the Polarization be negative?

No, the Polarization, measured in Polarizability cannot be negative.

Which unit is used to measure Polarization?

Polarization is usually measured using the Coulomb Square Centimeter per Volt[C*cm²/V] for Polarizability. Coulomb Square Meter per Volt[C*cm²/V] are the few other units in which Polarization can be measured.
