Anderson’s Bridge

Yanzu ina jin lalacewa na kungiyar Anderson’s bridge, ba da yaɗa Maxwell bridge da Hay’s bridge don kula tsari masu inganci. Yadda na iya amfani da Hay’s bridge da Maxwell bridge yana da gaba mai zurfi shi ne wadanda suka fi yiwuwar da kula tsari masu inganci mai kadan.

Amma, Hay’s bridge da Maxwell bridge suna da kyau a kula tsari masu inganci mai kasa da mafi yawa, saboda haka an buƙata kungiya da zai iya kula tsari masu inganci mai kadan, wannan kungiya ce ta ci gaba da Maxwell’s bridge da ake kira Anderson’s bridge.

Akwai, wannan kungiya ce ta ci gaba da Maxwell inductor capacitance bridge. A nan za a iya samun dole biyu a cikin kungiya a taka maɗa a kan capacitance da kuma canza maɗa a kan electrical resistance baki ɗaya.

An san shi da kyau saboda hanyar aikin inductors daga wurare micro Henry zuwa Henry. An kula maɗa inductor mai ba da shi a hakan a taka maɗa electrical resistance da capacitance da aka sani. Ina yi amsa a kan abu a kan circuit diagram of Anderson’s bridge (za a bayyana a cikin takarda).

A nan, inductor mai ba da shi an sama a kan baki ɗaya a kan a da r1 (wannan ce electrical resistance mai ba da shi).

Kungiyoyin bc, cd da da suna da electrical resistances r3, r4 da r2 kafin da suke electrical resistances. An sama capacitor mai sani a kan variable electrical resistance r da kuma an sama wannan a kan cd.

An sama supply a kan b da e.
A nan ina buƙatar amsa a kan l1 da r1:

A lokacin dole, akwai rawuwuka masu ma'ana waɗanda suka fi shahara su ne, su ne:

A nan za a iya samun voltage drops, za a iya samun:

A nan za a iya sama ic a kan abubuwa masu sauransu, za a iya samun:


Abubuwan da aka samu a nan (7) suna da ma'ana mafi yawan da aka samu a Maxwell bridge. A nan za a iya cewa don samun dole a gaba da ɗaya, ana bukatar a yi alternate adjustments of r1 da r a Anderson’s bridge.

A nan ina buƙatar amsa a kan inda za a iya samun maɗa inductor mai ba da shi a cikin labaran. A nan za a iya set frequency a kan signal generator a kan audible range. A nan za a iya same r1 da r har zuwa lokacin da phones ke ɓace kayayyakin.

A nan za a iya kula maɗa r1 da r (da aka samu a kan wannan adjustments) a kan multimeter. A nan za a iya amfani da abubuwan da aka samu a nan don samun maɗa inductor mai ba da shi. Zan iya kawo karin aiki a kan maɗa capacitor mai sani.

Phasor Diagram of Anderson’s Bridge

Ina bayyana voltage drops a kan ab, bc, cd, da ad a cikin e1, e2, e3 da e4 kamar yadda aka bayyana a cikin takarda.

A nan a cikin phasor diagram of Anderson’s bridge, ina bayyana i1 a kan reference axis. A nan ic tana fito a kan i1 saboda capacitive load an sama a kan ec, i4 da i2 suna fito a kan angle kamar yadda aka bayyana a cikin takarda.

A nan sumin da dukkan voltage drops, yadda e1, e2, e3, da e4 tana da e, wanda ake bayyana a cikin phasor diagram. Kamar yadda aka bayyana a cikin phasor diagram of Anderson’s bridge, sumin da dukkan voltage drops i1 (R1 + r1) da i1.ω.l1 (wanda ake bayyana a kan perpendicular to i1) tana da e1. e2 tana da i
