Physics

A certain super capacitor has a capacitance of 1.0F. The maximumvoltage is 2.7 V. It is contained in a 8.00mm diameter can that is13.00 mm long. It has two leads that are 3.50mm apart. It costs$0.29 when bought in bulk. How can such a large capacitance be madein a small container? The largest dielectric constant for oils isabout 90. The largest dielectric constant is about 100,000 inmaterial that costs $100,000/kg. Just describe the type of design(vacuum parallel-plate, dielectric parallel-plate, cylindrical,dielectric cylindrical, rolled parallel-plate, electrolytic,adjustable plate, etc.)
What is the energy density of the capacitor when fullycharged?
