How to Manually Calculate Chiller Capacity for Your Process
A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates.. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.
