An air-gap parallel-plate capacitor that has a plate area of1.60 m 2 and a separation of2.40 mm is charged to 110 V.
a) What is the electric field among the plates?
b) Decide the capacitance of this arrangement.
c) What is the electric energy density among the plates?
d) Find the total energy by multiplying your answer from Part (b)by the volume between the plates.
e) Compute the total energy from U =½CV 2, and compare your answer with yourresult from Part
