Impedance is a fundamentaltal concept in alternating current (AC) objects, presenting the e total opposition that a objectit presents to to thee flow of electric current. Unlike direct current (DC) objects, where resistance its the only factor, AC involve both resistance and reacte, making impedance a complex quantity.

Uzgodnienie impedancji

Impedance, denoted by the symbol the idel is the eng1; Xi1; FLT: 0 Xi3; Xi3; Z Xi1; Xi1; FLT: 1 Xi3; Xi3;, is measured in ohms (mbH) and can be expressed as a complex number:

Z = R + jX

In this equation:

  • (zob. pkt 2.2.1.1.1 niniejszego załącznika)
  • Xi1; Xi1; FLT: 0 Xi3; Xi1; Xi1; FLT: 1 Xi3; Xi3; is thee reactance (imaginary part).

Komponenty of Impedance

Oporność (R)

Oporność is te opposition tich flow of current due te colisions between oncors and atoms in a conductor. It is frequency-independent ande is a cucian contribuent in both AC and DC objects.

Reacance (X)

Reactance arises from the inductance and capacitance in AC objections. It varies with frequency and can be further divided into:

  • Xi1; FLT: 0 + 3; Xi3; Inductive Reactance (X Xi1; Xi1; FLT: 1 + 3; FLT: 1 + 3; Xi1; FLT: 2 + 3; Xi3;) FLT: 1; FLT: 3 + 3; XI3; FLT:: Oposition due to inductors, calculated as X XI1; FLT: 4 + 3; XI3; L XI1; XI1; FLT: 5 + 3; XI3; = 2πfL, wERE 1; XIF: 6 + 3; FLT: 6 + 3; FLT XI1; FLT: 7 + 3S; IDS 3S dividency and; XID 1; FLT: 8; FLT: 3; L X3; FLT: 1; FLT: 3; FLT: 3; FLT: 3; FLT; FLT; FLT: 3s;

Kalkulating Impedance

Te obliczenia te total impedance in a obwód, one mutt consider both resistance and reactance. The formula combines them im a prostokąty form:

Z = Â( R ² + X ²)

Alternatywne, impedance can also be expressed in polar form:

Z = 124; Z = 124; θ

Kiedy:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Xi124; Z Xi1; Xi1; FLT: 1 Xi3; Xi3; is the magnitude of impedance.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; θ XI1; Xi1; FLT: 1 Xi3; Xi3; is the fase angle, calculated as θ = arctan (X / R).
