Yadda aiki daidai na kawar wani aiki daidai na gida (AC) ta shafi ne daga lokacin da tashin aiki ya faruwa da tsari. Wannan matsala take faruwa a cikin aikins da suka samu koyar da inductor da capacitor da suka saukar daidai.

Don samun fahimtar da yake da wannan aiki daidai na gida, za a iya duba diagrammin aikin da aka bayyana a nan.

Za mu iya duba inductor da inductance L henries da kuma resistance R ohms, wanda ya saukar daidai da capacitor da capacitance C farads. Tashin aiki daidai V volts ya faruwa daga baya ga wadannan elementoda da suka saukar daidai.

A cikin wannan configuration na aiki daidai na gida, tashin aiki Ir zai faruwa da tsari kawai idan an tabbatar da hanyar equationi mai sauƙi.

Diagrammin Phasor

Diagrammin phasor na aikin da aka bayyana shine:

Za mu iya duba inductor da inductance L henries, wanda ya samu resistance R ohms, da suka saukar daidai da capacitor da capacitance C farads. Tashin aiki daidai V volts ya faruwa daga baya ga wannan combination na daidai na inductor da capacitor.

A cikin wannan setup na aiki, tashin aiki Ir zai faruwa da tsari kawai idan an tabbatar da hanyar equationi mai sauƙi.

Idan R yana da damar da L, maka frequency na resonance zai ce

Dabaminta Aiki Daidai Na Gida

A cikin aiki daidai na gida Ir = IL cosϕ ko

Saboda haka, impedance na aiki zai ba da sauƙi:

Daga cikin wannan bayanin aiki daidai na gida, za a iya karin abubuwan da za a iya duba:

 Impedance Characteristics

A cikin aiki daidai na gida, impedance na aiki yana faruwa da tsari. Wannan shine saboda terms na frequency-dependent wanda ke gudanar da inductors da capacitors a cikin aiki daidai na gida sun haɗa, wanda ya biyo da tsari. Idan inductance (L) ana yi a henries, capacitance (C) a farads, da kuma resistance (R) a ohms, impedance na aiki Zr tana yi a ohms.

High Impedance Value

Magnitude na Zr yana da damar. A cikin point na aiki daidai na gida, ratio L/C yana faruwa da damar, wanda ya biyo da impedance na aiki. Wannan high impedance shine feature na haske wanda ke shirya aiki daidai na gida daga wasu.

 Low Circuit Current

Daga formula na circuit current Ir = V/Zr, da kuma damar na Zr, tashin aiki Ir yana da damar. Kafin supply voltage V yana da damar, high impedance yana haifar da tashin aiki, wanda ya ci gaba tashin aiki daga source.

 Branch Current vs. Line Current

Tashin aiki da suka faruwa daga capacitor da inductor (coil) suka da damar da line current. Wannan shine saboda impedance na branch (inductor-resistance combination da capacitor) yana da damar da overall circuit impedance Zr. Saboda haka, damar da tashin aiki yana iya faruwa a cikin wannan branches musamman bincika da tashin aiki da suka faruwa daga main line na aiki.

Rejector Circuit Nature

Saboda kyakkyawan tashin aiki da power daga electrical mains, aiki daidai na gida ana nufin "rejector circuit." Wannan yana da kyakkyawa.
