Lesson 5 Physics 2 Quarter 3

Capacitance and Dielectrics

Capacitor

It is the device that has a capacity to store electric charge

Capacitor

It is made up of two conducting objects placed nearby each other but connected

electrical energy

Capacitor is like a battery, they both store ?

Battery

inside a ?, chemical reactions make electrons move on one terminal and then absorb electrons on the other

Capacitor

This does not make electrons move, it just store them

Capacitance

It is the ability of a capacitor to store an electric charge per unit of voltage across its place of a capacitor

Farad

What is the unit for capacitance?

C/V

Farad is equal to ?

parallel-plate, cylindrical, concentric, circular

What are some types of capacitor (ppt)?

Dielectric

A non-conducting material placed between plates of capacitor to enhance its electrical properties

K

dielectric constant has a symbol ?

dielectric

the dielectric constant is associated with the electric nature of ?

materials

different ? contribute to the variation of dielectric constant

C=q/V

capacitance formula

C=EoA/d

capacitance formula for parallel-plate capacitor
