Assignment:
A parallel-plate capacitor with plate area of 2 m^2 and a separation of 1.0 mm is charged to 100 V.
(a) What is the electric field between the plates?
(b) What is the energy per unit volume in the space between the plates?
(c) Find the total energy by multiplying your answer from part (b) by the total volume between the plates.
(d) Find the capacitance of C.
(e) Calculate the total energy from U=1/2CV^2, and compare your answer with the result from part (c).
