A 12.0-V battery (potential source) is connected across a 6.00-F air-filled capacitor.
 
  (a) How much energy can be stored this way?
  (b) How much excess charge is on each plate of the capacitor?

Question 2

An air-filled parallel-plate capacitor is constructed with a plate area of 0.40 m2 and a plate separation of 0.10 mm.
 
  It is then charged to a potential difference of 12 V? (0 = 8.85  10-12 C2/N  m2 )
  (a) How much charge is stored on each of its plates?
  (b) How much energy is stored in it?
