Ch. 19: Electrical Fields & Capacitors

Reading
BJU Physics Ch. 19
AP Classroom: We will continue with practice tests. Time yourself. 

The Big Ideas
  • ​An Electric Field can be visualized by plotting the paths of a hypothetical positive-charged particle placed in the vicinity of one or more charged objects.
  • The electric field strength is E = kQ/d^2. The units are Newtons. 
  • Volts is potential-energy per Coulomb: V = J/C.  A 1-Volt potential stands ready to do 1-Joule of work on a 1-Coulomb particle, moving it against an electric field. 
  • Capacitors store electric energy in the form of an internal electric field. 
  • A capacitor blocks direct current, but passes alternating current. The higher the frequency, the more current passes through a capacitor. This is the opposite effect of a coil. More on that in Ch. 22.
