• Inserting a dielectric material between two
  charged parallel conducting plates, originally
  separated by air and now disconnected from the
  battery, will
• (1) Increase the charge on the plates.
• (2) Increase the capacitance of the plates.
• (3) Increase the voltage across the plates.
• (4) None of the above.
