Cosa (chi) è output impedance - definizione


Output impedance         
MEASURE OF THE OPPOSITION TO CURRENT FLOW, BOTH STATIC AND DYNAMIC, INTO THE LOAD NETWORK BEING CONNECTED THAT IS INTERNAL TO THE ELECTRICAL SOURCE
Internal impedance; Source impedance; Output resistance; Source resistance; Battery Conductance; Battery conductance
The output impedance of an electrical network is the measure of the opposition to current flow (impedance), both static (resistance) and dynamic (reactance), into the load network being connected that is internal to the electrical source. The output impedance is a measure of the source's propensity to drop in voltage when the load draws current, the source network being the portion of the network that transmits and the load network being the portion of the network that consumes.
Electrical impedance         
  • complex impedance plane]]
  • load]] <math>Z</math>, driving a current <math>I</math>
  • Generalized impedances in a circuit can be drawn with the same symbol as a resistor (US ANSI or DIN Euro) or with a labeled box.
  • The phase angles in the equations for the impedance of capacitors and inductors indicate that the voltage across a capacitor ''lags'' the current through it by a phase of <math>\pi/2</math>, while the voltage across an inductor ''leads'' the current through it by <math>\pi/2</math>. The identical voltage and current amplitudes indicate that the magnitude of the impedance is equal to one.

In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.Slurzberg; Osterheld (1950).
