8.4: Energy Stored in a Capacitor

To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq). This work becomes the energy stored in the electrical field of the capacitor. In order to charge the capacitor to a charge Q, the total work

OverviewHistoryMethodsApplicationsUse casesCapacityEconomicsResearch

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. En
