Example Formula

The formula for the capacitance (C) of a parallel plate capacitor is given by:

C = ε × A / d


  1. C: Capacitance of the capacitor
  2. ε: Permittivity of the material between the plates
  3. A: Area of one of the plates
  4. d: Separation distance between the plates

Who wrote/refined the formula

The concept of capacitance was first introduced by the English scientist Michael Faraday in the 19th century. However, the specific formula for the capacitance of a parallel plate capacitor is a natural consequence of the physics of electromagnetism and has been refined over time with the progress of our understanding of electric fields and conductors.

Real Life Application

Parallel plate capacitors are used in many practical applications, such as tuning radios to specific frequencies, power supply filters to smooth out the output from power supplies, and in defibrillators to deliver a sudden burst of energy.
