Admittance: Me kana? (Takaitaccen & Admittance da Impedance)

Mai Suna Da Admittance?

Admittance yana nufin hanyar da take da shawarar kimiyya ko karamin abubuwa zai iya gudanar da karami ta huka. Admittance yana cikin impedance (matsayin mafi girma), kamar haka da conductance da resistance suna da shiga. Unit SI na admittance shine siemens (symbol S).

Don ya fi bayyana wannan takaitaccen bayani: mari da ba da damar muhimman kalmomi wadanda suka taimaka da admittance. Dukuna saboda resistance (R) yana da girma baki daya amma babu tsari. Zan iya cewa shi ne matsayin yadda ake koyar da karami.

A cikin circuit na AC; a kan resistance, an samun biyu masu koyar (inductance da capacitance) zai iya duba. Saboda haka an samu kalmomin impedance wanda yana da shiga daban-daban kamar resistance amma yana da girma da tsari. Tsari na biyu shine resistance, amma tsari na uku shine reactance, wanda yake rage da koyarin karami.

Idan an doke admittance zuwa impedance, admittance yana cikin inverse (i.e. reciprocal) na impedance. Saboda haka yana da shiga mafi yawan cikin impedance. Saboda haka za a iya cewa shi ne matsayin yadda ake koyar da karami wadanda karamin abubuwa ko circuit ta iya gudanar da ita. Admittance tana da shiga mafi yawan cikin dynamic effects of susceptance na material zuwa polarization amma an samu a Siemens ko Mho. Oliver Heaviside ya bayyarta wannan a Disamba 1887.

Bayyana Admittance Daga Impedance

Impedance yana da tsari na biyu (resistance) da tsari na uku (reactance). Symbol na impedance shine Z symbol, amma symbol na admittance shine Y symbol.

Admittance yana da complex number kamar impedance wanda yake da tsari na biyu, Conductance (G) da tsari na uku, Susceptance (B).

(yana da minus don capacitive susceptance da plus don inductive susceptance)

Admittance Triangle

Idan akwai circuit wanda yake da Resistance da Capacitive reactance a series kamar yadda ake bayyarta a nan.

Admittance na Circuit na Parallel

Akwai circuit wanda yake da biyu branches A da B kamar yadda ake bayyarta a nan. 'A' yana da inductive reactance, XL da resistance, R1 amma 'B' yana da capacitive reactance, XC da resistance, R2. voltage, V an sanya ta zuwa circuit.
