Impedance 01
Impedance 01 : (1) (Electr) Total opposition, consisting of ohmic resistance and reactance, to the flow of an alternating electrical current. (2) (Phys) The ratio of a force-like quantity to a velocity-like quantity, such as pressure to flow rate, temperature to heat flow, or sound pressure to particle displacement. Note: The term is used similarly in electronics, mechanics, and acoustics
