ALL meanings of impedance
im·ped·ance
I i - noun impedance electricity: opposition to current 1
- noun Definition of impedance in Technology (electronics, physics) Opposition to flow of alternating current. Impedance consists of resistance plus reactance (capacitive or inductive). Measured in Ohms. 1
- noun impedance Electricity. the total opposition to alternating current by an electric circuit, equal to the square root of the sum of the squares of the resistance and reactance of the circuit and usually expressed in ohms. Symbol: Z. 1
- noun impedance Also called mechanical impedance. Physics. the ratio of the force on a system undergoing simple harmonic motion to the velocity of the particles in the system. 1
- noun impedance something that impedes; an obstacle or hindrance. 1
- noun impedance The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance. 1
- noun impedance (physics) 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. 0
- noun impedance (physics) A quantity analogous to electrical impedance in some other energy domain. 0
- noun impedance (by analogy, software engineering, usually with “mismatch”) a measure of the opposition caused by differences between two paradigms, especially between object-oriented development and relational databases. 0
- noun impedance a measure of the opposition to the flow of an alternating current equal to the square root of the sum of the squares of the resistance and the reactance, expressed in ohms 0
- noun impedance a component that offers impedance 0
- noun impedance the ratio of the sound pressure in a medium to the rate of alternating flow of the medium through a specified surface due to the sound wave 0
- noun impedance the ratio of the mechanical force, acting in the direction of motion, to the velocity of the resulting vibration 0
- noun impedance the total opposition offered by an electric circuit to the flow of an alternating current of a single frequency: it is a combination of resistance and reactance and is measured in ohms 0
- noun impedance the ratio of the force per unit area to the volume displacement of a given surface across which sound is being transmitted 0
- noun impedance Impedance is a measure of the opposition to electrical flow, that is measured in ohms. 0
- noun impedance The symbol Z is used for impedance. 0
