Question
A parallel-plate capacitor is made of two square plates 30 cm on a side and 1 mm apart. The capacitor is
connected to a 90-V battery.
Hint
a. What is the energy stored in the capacitor?
Energy stored in the capacitor is 3.2E-6
X µJ.
b. With the battery still connected, the plates are pulled apart to a separation of 2 mm. What is the
energy stored in the capacitor now?
Energy now stored in the capacitor is 1.075275E-5
X µJ.
c. This time, starting from situation in (a), with the batteries disconnected (but capacitors still
charged), the plates are pulled apart to a separation of 2 mm. What is the energy stored in the
capacitor now?
Energy now stored in the capacitor is
µJ.
d. Comparing your results in (b) and (c) above, it makes sense that the energy stored in the capacitor
increases in (c), because the work done in
potential energy.
arating the plates is stored as the electrostatic
In (b), why does the energy decrease even though work is done in separating the plates?
