What you'll learn

  1. Weaker inside: A slab weakens the field
  2. The slab's face charge: The face charge: Q(1 − 1/K)
  3. Fill it, battery on: Battery on: V stays, Q grows
  4. Fill it, battery off: Battery off: Q stays, U falls
  5. Spark limit: Dielectric strength: a field limit
  6. Metal sheet: A metal sheet removes its thickness
  7. Half the gap: Slab and air in series
  8. Keep the capacitance: A slab acts like a thinner gap
