MathLiveParallel plate capacitor capacitance
Gives the capacitance of an ideal capacitor made of two large flat parallel plates separated by a dielectric, neglecting edge effects. It is used to size capacitors from plate area, plate separation and the permittivity of the material between the plates.
C=\frac{\varepsilon_0 \varepsilon_r A}{d}What the symbols mean
