PPT-Capacitance and Dielectrics

AP Physics C Capacitors A capacitor consists of 2 conductors of any shape placed near one another without touching It is common to fill up the region between these 2 conductors with an insulating material called a dielectric.

Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5 Chapter 24 What is Capacitance? • Capacitance (C) is equal to the Charge (Q ) between two charges or charged “regions” divided by the Voltage (V) in those regions͘  I have a . supercapacitor. whose capacitance is 1 Farad. This means. a current of 1 Amp flows through it when 1 Volt is applied across it.. 1 Coulomb is separated by 1 . metre. .. 1 Joule flows through it in 1 second.. Chapter 20. Topics in this .
