Maimaita Tattalin Karamin Kirkiya

An koyar da tushen bayanan mesh current, ana amfani da ita don tushen da kawo shiga kafuwar kashi da sarrafa masu kayayyakin ko kafuwar kashi da sarrafa masu mesh (loop) da ke ciki da voltage ko karamin kashi. Wannan yadda ake kira Loop Current Method, ya haɗa da ake bayar da karamin kashi daban-daban da na mesh, sannan ake tsara alamomin voltage da suka yi a kan abubuwan da ake iya a mesh ba haka a gaba-gabanta da ake bayar da mesh current.

A tushen mesh current, mafi yawan ji amsa suna da karamin kashi a mesh daban-daban, sannan hukuma mai ban sha'awa shine Kirchhoff's Voltage Law (KVL), wanda ya ce:
"A nan kafuwar kashi mai karfi, nettaren voltage da ake amfani da shi zai iya kasance jami'an zaruratun karamin kashi da resistance. Kuma, a gaba-gabanta da karamin kashi, jami'an voltage da suka ci a kan loop zai iya kasance jami'an voltage da suka rage."

Ba za a fahimta metoda na Mesh Current ta haka, zan iya nuna wannan kafuwar kashi:

A Nan Kafuwar Kashi

• R₁, R₂, R₃, R₄, da R5 suna da muhimmanci da take.

• V₁ da V₂ suna da voltage sources.

• I₁ shine karamin kashi da ke ciki a mesh ABFEA.

• I₂ shine karamin kashi da ke ciki a mesh BCGFB.

• I₃ shine karamin kashi da ke ciki a mesh CDHGC.

• Don yakin aikin tushen, ake bayar da karamin kashi a mesh daban-daban a gaba-gabanta da sa'a.

Muhimmanci don Tushen Kafuwar Kashi via Metoda na Mesh Current

A nan kafuwar kashi, wannan muhimmanci suna nuna yanayin tushen mesh current:

Muhimmanci 1 – Idana Meshes/Loops Mai Tsawo

Na farko, idana meshes mai tsawo. A nan kafuwar kashi akwai mesh uku, wadanda ake duba don tushen.

Muhimmanci 2 – Yana Bayar Da Karamin Kashi zuwa Har Mesh

Bayar da karamin kashi zuwa har mesh, kamar yadda ake nuna a kafuwar kashi (I₁, I₂, I₃ ke ciki a har mesh). Don yakin aikin tushen, ya fi kyau a bayar da duk karamin kashi a gaba-gabanta da sa'a.

Muhimmanci 3 – Yanayin KVL Equations zuwa Har Mesh

Saboda akwai mesh uku, za a samun KVL equations uku:

Amfani da KVL zuwa Mesh ABFEA:

Muhimmanci 4 – Zaba Equations (1), (2), da (3) tare da zama don samun darajin karamin kashi I₁, I₂, da I₃.

Idan an samu karamin kashi na mesh, za a iya samun darajin voltage da karamin kashi a kafuwar kashi.

Matrix Form

A nan kafuwar kashi za a iya samun da amfani da metoda na matrix. Matrix form na Equations (1), (2), da (3) ya faruwa a haka:

Da,

• [R] shine mesh resistance

• [I] shine column vector na mesh currents and

• [V] shine column vector na algebraic sum of all the source voltages around the mesh.

Wannan shine duka game da metoda na mesh current analysis.
