A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them. After the plates are 2d apart, the magnitude of the charge on the plates and the potential difference between them are what?
   
  a.
  Q0, V0
   
  b.
  Q0, V0
   
  c.
  Q0, V0
   
  d.
  Q0, 2V0
   
  e.
  2Q0, 2V0

Question 2

If VA  VB = 50 V, how much energy is stored in the 54-F capacitor?
 
   


   
  a.
  50 mJ
   
  b.
  13 mJ
   
  c.
  28 mJ
   
  d.
  8.9 mJ

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
