 * 2)   A measure of the opposition to the flow of an alternating current in a circuit; the aggregation of its resistance, and inductive and capacitive reactances; the ratio of voltage to current treated as complex quantities.
 * 3)   A quantity analogous to electrical impedance in some other energy domain
 * 4)  a measure of opposition to motion of something subjected to a force; the ratio of force to velocity treated as complex quantities.
