Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.
Energy intensity is defined as the ratio of energy consumption to some measure of demand for energy services. The choice of a measure of demand for energy services (a demand indicator) in efficiency analysis is critical.nergy intensity is defined as the ratio of energy consumption to some measure of demand for energy services.
