A capacitor is not the most efficient device for storing energy.Batteries can store more energy in much less space. For example, atypical 12 V automobile battery stores on the order of 1.00 106J.
(a) Find the capacitance necessary to store 1.00 106 J with apotential difference of 1.00 104 V across the capacitor'sterminals.
1________________
(b) Suppose that such a capacitor was made in the form of aparallel-plate capacitor with a vacuum between the plates and anelectric field no greater than 7.00 106 V/m. What is the minimumarea of the plates?
2 ________________
And.........
The plates of a parallel-plate capacitor each have an area of 0.1m2 and are separated by a 1 mm thick layer of paper. The capacitoris connected to a 11 V battery. (The dielectric constant for paperis 4.)
