Electrical elastance refers to the capacity of an electrical circuit or device to store energy in an electric field. Synonyms for this term include electrical capacitance, electrical capacity, and electrical charge storage. These terms all refer to the ability of a system to store and release electrical energy, and they are often used interchangeably in discussions of electrical engineering. Other related terms include electrical impedance, which describes the resistance of an electrical circuit to the flow of current, and electrical reactance, which describes the ability of a circuit to resist changes in current flow. Understanding these concepts is crucial for designing and troubleshooting complex electrical systems.
