Cikin Yakin Heaviside Bridge

Amsa da muka so in bazu wannan bridge ya kamata a nemi karin bayani game da yadda ake amfani da indukta mutanen a cikin circuits na bridge. Idan yadda ake amfani da mutual inductance yana haifar da muna, amsar da ta ke shiga shine muna za a yi amfani da wannan indukta mutanen a Heaviside bridge circuit. Ana amfani da indukta mutanen mai tsari don samun daraja na indukta mutanen mai wani a wasu circuits. Indukta mutanen ana amfani a wasu circuits domin ya shafi daraja na self inductance, capacitance da kuma frequency waɗanda suka.
Amma a wasu industries, ba ake amfani da indukta mutanen don samun daraja na self inductor ba saboda akwai wasu hanyoyi masu zama da inganci don samun self inductor da capacitance, kuma wasu hanyoyi masu iya haɗa da amfani da capacitor mai tsari wadanda suke samu a kan kudin. Amma akwai wasu abubuwa da zai iya haifar da amfani da indukta mutanen a wasu halayyoyi, amma wannan tashar ita ce mai yawa.

An yi waƙoƙi masu kayayyaki a kan amfani da indukta mutanen a cikin circuits na bridge. Don in fahimtar kimaɗi na Heaviside bridge, muna buƙata zuwa samun ƙimiɗar tare da self inductor da indukta mutanen a biyu coils da aka gudanar da su a cikin series combination. A nan muna buƙatar samun rubutu na indukta mutanen a kan self inductance.
Za mu iya duba biyu coils da aka gudanar da su kamar yadda ake nuna a cikin hoton.

Idan magnetic fields suna ƙara, inda muna iya kula ƙarin indukta daga biyu waɗannan ita ce

Idan L1 shine self inductor na coil na farko,
L2 shine self inductor na coil na biyu,
M shine indukta mutanen daga biyu coils.
Idan an yi gaba-gaban ƙofin wani na waɗannan coils, muna ga

Idan muna kula waɗannan biyu equations, muna ga

Saboda haka, indukta mutanen daga biyu coils da aka gudanar da su a cikin series ita ce ƙarin kadan daga tasiri na self inductor da aka samu a lokacin da ƙarin magnetic fields suna ƙara, da tasiri na self inductor da aka samu a lokacin da ƙarin magnetic fields suna ƙaramin gaba.

Amma, muna buƙatar da biyu coils a kan ƙaramin axis don samun ƙarin ƙarfin daidai. Za mu iya duba circuit na Heaviside mutual inductor bridge,

Fadin amfani na wannan bridge a kan industries shine samun indukta mutanen a kan self inductance. Circuit na wannan bridge tana da four non inductive resistors r1, r2, r3 da r4 da aka gudanar da arms 1-2, 2-3, 3-4 da 4-1 respectively. A cikin series na wannan bridge circuit, an gudanar da unknown mutual inductor. An yi amfani da voltage across terminals 1 and 3. A balance point, electric current da ya shiga 2-4 ita ce zero, saboda haka voltage drop across 2-3 ita ce equal to voltage drop across 4-3. Saboda haka, idan muna kula voltage drops of 2-4 and 4-3, muna ga,

Kuma muna ga,

da kuma indukta mutanen ita ce,

Za mu iya duba wasu halayyar ma'aikiyi,

A wannan halayya, indukta mutanen ya zama

Idan muna iya duba circuit na Campbell’s Heaviside bridge:

Wannan shine Heaviside bridge mai girma. Wannan bridge tana amfani don samun daraja na self inductor a kan mutual inductance. Girman yana cikin addition of balancing coil l, and R a arm 1 – 4, kuma electrical resistance r tana gudanar da arm 1-2. Short circuit switching tana gudanar da r2 and l2 don samun biyu sets of readings, wanda ake yi a lokacin da short circuiting r2 and l2 da wanda ake yi a lokacin da open circuiting r2 and l2.

Idan muna iya kula rubutu na self inductor don wannan girman Heaviside bridge. Kuma za mu iya ƙara da cewa daraja na M da r a lokacin da switch yana daɗe shine M1 and r1, M2 and r2 a lokacin da switch yana magance.
A lokacin da switch yana daɗe, muna ga a balance point,

kuma a lokacin da switch yana magance, muna iya rubuta

Saboda haka, muna ga rubutu na self inductor
