Polystyrene has dielectric constant 2.6 and dielectric strength 2.0 × 107 v/m. a piece of polystyrene is used as a dielectric in a parallel-plate capacitor, filling the volume between the plates. part a when the electric field between the plates is 75 % of the dielectric strength, what is the energy density of the stored energy?

2,589 J/m³

This is a matter of calculating the energy density of stored energy in a parallel-plate capacitor.

Given:

Question:

The energy density

The Process:

The expression for the energy density inside a dielectric  is

Permittivity, i.e., with vacuum permittivity

Let's calculate the permittivity and the electric field.

Both data are substituted into the formula to calculate the energy density of stored energy.

Hence, we get

Keywords: polystyrene, dielectric constant, strength, a parallel-plate capacitor, electric field, energy density, the stored energy, relative permittivity, vacuum

i think the answer is a, hope this : )

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
