Electrical elastance
Electrical elastance is the inverse of capacitance. The SI unit is the reciprocal farad. Although the term daraf is sometimes used, this is not approved by SI. Electrical inductor-capacitor-resistor circuits can be converted to mass-spring-damper systems. If voltage is taken to be force and current velocity, elastance corresponds to the elastic constant of a spring.
