  1. What does a capacitor do?
    Has the capacity to store charge and enegy.
  2. What is the capacity of a capacitor?
    C = Q/V
  3. What is the capacity of a parallel plate capacitor?
    C = Aε/d
  4. If inside of a capacitor distance "d" between two plates is made smaller, what happens to the Capacity?
    Increases
  5. What is the unit for Capacitors?
    C/V aka Farad
