[amp_mcq option1=”Farad\/sq-m” option2=”Farad\/meter” option3=”Weber\/meter” option4=”Weber\/sq-m” correct=”option1″]<\/p>\n
The correct answer is A. Farad\/sq-m.<\/p>\n
Permittivity is a measure of how much electric field is required to create a given electric displacement in a material. It is a dimensionless quantity, but it is often expressed in units of farads per square meter (F\/m).<\/p>\n
A farad is the unit of capacitance, which is the ability of a material to store an electric charge. The permittivity of free space, $\\epsilon_0$, is a fundamental constant of nature that has the value $8.854\\times10^{-12}$ F\/m.<\/p>\n
The permittivity of a material, $\\epsilon$, is related to the permittivity of free space by the equation $\\epsilon=\\epsilon_0\\epsilon_r$, where $\\epsilon_r$ is the relative permittivity of the material. The relative permittivity is a dimensionless quantity that is greater than or equal to 1. It is a measure of how much more easily an electric field can be created in a material than in free space.<\/p>\n
The permittivity of a material is important in many areas of physics and engineering, including electromagnetism, optics, and electronics.<\/p>\n","protected":false},"excerpt":{"rendered":"
