Admittivity is a technical term widely used in electrical and electronic engineering. However, for those seeking alternative words or synonyms to convey a similar meaning, capacitive reactance can be a suitable substitute. This term indicates the opposition to the flow of alternating current due to the presence of capacitance in a circuit. Another related term is permittivity, which refers to the ability of a material to store electrical energy in an electric field. Both capacitive reactance and permittivity are closely linked to admittivity, and can be used interchangeably in certain contexts, providing greater flexibility when discussing electrical properties and phenomena.
