A parallel-plate capacitor having plate area 20 cm2 and separation between the plates 1.00 mm is connected to a battery of 120 V. The plates are pulled apart to increase the separation to 2.0 mm
a Calculate the charge flown through the circuit during the process. b How much energy is absorbed by the battery during the process?
c Calculate the stored energy in the electric field before and after the process.
d Using the expression for the force between the plates, find the work done by the person pulling the plates apart.
e Show and justify that no heat is produced during this transfer of charge as the separation is increased.
