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
