impedance
The combined effect of capacitance, inductance, and resistance on a signal According to Ohm’s law, voltage is the product of current and resistance at a given frequency Impedance is a measure of resistance to electrical current flow when a voltage is moved across it Impedance is measured in ohms and is the ratio of voltage to the flow of current allowed
The apparent resistance in an electric circuit to the flow of an alternating current, analogous to the actual electrical resistance to a direct current, being the ratio of electromotive force to the current
The total opposition that a circuit offers to the flow of current at a particular frequency It is a combination of resistance (R) and reactance (X) and is measured in ohms
the sound pressure divided by the particle velocity and the surface area through which an acoustic wave propagates
Similar to electrical resistance, since it is a measure of the opposition to the flow of electricity Impedance is meaningful only for alternating current, and changes value as the frequency of the electricity changes
- A measurement, in ohms, of the resistance a component presents to the flow of electrical current; the lower the number, the lower the resistance Speaker impedance is especially important when determining amplifier compatibility
The electrical characteristic of an electronic device that reflects the voltage developed in response to a current supplied to the device High impedance receiver inputs respond with less power demand upon a received input signal Low impedance speakers permit higher power drive from a given amplifier output voltage
  a measure of the total opposition to current flow in an alternating current circuit measured in ohms   When applied to speakers, impedance is the load that a speaker places on the power amplifier   A low impedance device draws a high current flow from a source such as a power amplifier; higher impedance sources draw less   
the opposition of a circuit or speaker to ac current; the combined effect of a speaker's resistance, inductance, and capacitance that opposes the current fed to it It is measured in ohms and varies with the frequency of the signal
a material's opposition to the flow of electric current; measured in ohms
Resistance to the flow of alternating current (e g , The resistance of a speaker’s voice coil may be measured at 3 1 ohms, but the impedance of that speaker may be 10 ohms at 50 Hz )
a measure of the power of a piece of electrical equipment to stop the flow of an alternating current
a measure of opposition to motion of something subjected to a force
  The total passive opposition offered to the flow of electric  current Note 1:  Impedance is determined by the particular combination of resistance, inductive reactance, and capacitive reactance in a given circuit   (188)  Note 2:   Impedance is a function of frequency, except in the case of purely resistive networks
a measure of the opposition caused by differences between two paradigms, especially between object oriented development and relational databases
The total opposition (i e , resistance and reactance) a circuit offers to the flow of alternating current at a given frequency
For an inductive circuit, X = 2πfL, where f = frequency and L = self-inductance; for a circuit with capacity X = 1 ÷ 2πfC, where C = capacity
The total opposition that a battery offers to the flow of alternating current Impedance is a combination of resistance and reactance
total opposition to flow of current, measured in ohms; combined effort of resistance, inductance, and capacitance
The total opposition (i e resistance and reactance) a circuit offers to the flow of alternating current It is measured in ohms, and the lower the ohmic value, the better the quality of the conductor
