PHYSICS / ELECTROSTATICS
Estimate capacitance from plate area, separation, and dielectric relative permittivity. Inspect the governing equation, substituted SI values, output, and model boundaries in one guided workspace.
Use boundary
Estimate capacitance from plate area, separation, and dielectric relative permittivity. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
C = epsilon_0 epsilon_r A/d

Use boundary
Plates are large, parallel, uniformly separated, and fringing fields are neglected.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
