Parallel-Plate Capacitance

Capacitance from plate area and separation.

Formula

C=ε0AdC = \frac{\varepsilon_0 A}{d}

Variables

APlate area
dSeparation
\varepsilon_0Permittivity

Did You Know?

Bringing capacitor plates closer boosts capacitance, the trick that shrinks the huge capacitors of a century ago.
