# Simple Capacitance Problem: Teflon-Filled Parallel-Plate Capacitor Calculation

• physics213
In summary, the conversation discusses a problem involving a Teflon-filled parallel-plate capacitor with a plate area of 175 cm2 and insulation thickness of 0.0500 mm. The student is asked to determine the capacitance and maximum voltage for the capacitor. The student is unsure of the purpose of the insulation thickness, but it is later clarified that it acts as a dielectric. Resources, such as a data sheet from DuPont, can be used to find the properties of the Teflon and solve the problem.

## Homework Statement

For a TeflonTM-filled parallel-plate capacitor having a plate area of 175 cm2 and insulation thickness of 0.0500 mm, determine the following:

a.)capacitance
b.)max volatge

## Homework Equations

C = Q/V

C = (constant)(A/d)

## The Attempt at a Solution

I understand the gist of this problem but I don't understand what the "insulation thickness" is supposed to do in this problem. Please help! thanks.

I would read it as Teflon filled and the insulation thickness then would be the separation of the plates.

Not sure what resources you are supposed to employ to determine the properties of the Teflon in the problem, but here is a data sheet from DuPont for the electrical properties.

Yeah I see now. The Teflon acts as a dielectric and from there it isn't too hard to find the Voltage and Capacitance. Thanks a lot again!

## What is capacitance?

Capacitance is the ability of a system to store an electric charge. It is measured in units of Farads (F).

## How do you calculate capacitance?

Capacitance can be calculated using the equation C = Q/V, where C is the capacitance in Farads, Q is the charge in Coulombs, and V is the voltage in Volts.

## What is a simple capacitance problem?

A simple capacitance problem involves determining the capacitance of a system or finding the charge or voltage given the capacitance and other known values.

## What are some common applications of capacitance?

Capacitance has several applications, including in electronic circuits, power factor correction, energy storage, and sensing devices.

## How does capacitance change with different factors?

The capacitance of a system is affected by the distance between the plates, the surface area of the plates, and the type of material used. It also increases with the increase in the dielectric constant of the material between the plates.
