The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.

ceramic capacitor based on temperature stability, but there is more to consider if the impact of Barium Titanate composition is understood. Class 2 and class 3 MLCCs have a much higher BaTiO 3 content than Class 1 (see table 1). High concentrations of BaTiO 3 contributes to a much higher dielectric constant, therefore higher capacitance values …
