Supercapacitors benefit from large effective surface areas and small electrode separation distances. A typical small supercapacitor (produced by Maxwell Industries, San Diego, CA) has a capacitance of $100 \mathrm {~F}$. It is a cylindrical device with a length of $4.5 \mathrm {~cm}$ and a diameter of $2.2 \mathrm {~cm}$. What are the dimensions of a $100 \mathrm {~F}$ traditional parallel plate capacitor (with a square geometry) that uses an electrolyte with a dielectric constant $\varepsilon _ { \mathrm { r } } = 2.0$ and has a plate separation of $0.01 \mathrm {~mm}$ ?
