Energy Stored by a Capacitor (7.4.3) | AQA A-Level Physics

Calculating Energy Stored in a Capacitor. The energy (E) stored in a capacitor is a function of its charge (Q), potential difference (V), and capacitance (C). There are three primary formulae for calculating this energy: 1. E = 1/2 QV: Shows energy as proportional to the product of charge and potential difference. 2.

Stored Electrical Energy

Carefully release all stored energy as part of the de-energizing process and be mindful that many types of machinery contain more than one energy source.
