Which one is correct option?
  1. A pure capacitor never dissipates energy, but only stores.
  2. Capacitor can store finite amount of energy even cunent is zero.
  3. The current through a capacitor is zero if voltage across it d.c.
  4. Voltage across a capacitor cannot change instantaneously since it would require an infinite current.
  5. qc(0-) = qc(0+)
