Kanun Yadda Kirchhoff Current da Kanun Yadda Kirchhoff Voltage
Akwai tushen da dama a cikin karamin kware da voltage na farkon circuit. Wannan tushen suna da shawarwa da wasu kananan al'adun da ake kira Kirchhoff laws ko kuma Kirchhoff Current and Voltage laws. Wasu kananan al'amuran ya fi yawa wajen samun resistance ko kuma impedance (a cikin AC) na gaban network mai zurfi da karamin kware da ke fara a farkon network. Guatov Robert Kirchhoff ya fi yawa wannan kananan al'adun, saboda haka ana kiran su ne Kirchhoff Laws.
Kirchhoff’s Current Law
A cikin circuit, karamin kware ta zama a cikin abubuwan elektriki. A bincike karamin kware a cikin abubuwan elektriki, a bincike karamin kware da ke fara a cikin abubuwan elektriki, ita ce mafi yawan karamin kware da ke fara a cikin abubuwan elektriki. Binciken yana iya a yi a matsayin yanayi a cikin circuit.
Idan binciken yana a cikin conductor da karamin kware ke fara, akwai karamin kware da ke fara a cikin binciken, ko kuma in iya cewa karamin kware da ke fara a binciken, za a fara a binciken. Idan binciken yana a matsayin yanayi a cikin circuit, ya kamata a yi a matsayin yanayi a cikin junction a cikin circuit.
Saboda haka, mafi yawan karamin kware da ke fara a cikin junction, ita ce mafi yawan karamin kware da ke fara daga junction. Wannan shine abubuwan da ake amfani da su a cikin karamin kware. Kirchhoff Current law ya kiran wannan abubuwa. Ana kiran wannan kananan al'amuran da kuma Kirchhoff First Law. Wannan kananan al'adu ya ce, a matsayin yanayi a cikin electrical circuit, jumla duka branch currents tare da zero. Idan an kira duka currents da ke fara a cikin junction da positive, akwai convention da ke fara daga junction da negative. Idan an summa duka waɗannan positive da negative signed currents, ba a tabbas, za a sami result of zero.
An rubuta Kirchhoff’s Current Law a cikin form na masu ilimi, a nan:
A nan junction da n number of beaches ke fara a matsayin yanayi.
Lets,
Karamin kware a cikin branches 1, 2, 3 …. m suna fara a cikin junction.
Amma karamin kware a cikin branches
sun fara daga junction.
Saboda haka, karamin kware a cikin branches 1, 2, 3 …. m zan iya a kira positive a cikin general convention, kuma karamin kware a cikin branches
zan iya a kira negative.
Saboda haka, duka branch currents a cikin junction –
Duk da haka, jumla duka currents a cikin junction –
Wannan tana iya a kira zero a cikin Kirchhoff Current Law.
Saboda haka,
An rubuta Kirchhoff First Law a cikin form na masu ilimi ∑ I = 0 a matsayin yanayi a cikin electrical network.

Kirchhoff’s Voltage Law
Wannan kananan al'adu tana da muhimmanci a cikin voltage drops a cikin farkon electrical circuit. Sannan a nan yanayi a cikin closed loop a cikin electrical circuit. Idan wanda yake zuwa yanayi na biyu a cikin same loop, yana iya a samu cewa potential a cikin yanayi na biyu yana iya a bangarance da yanayi na uku. Idan yake zuwa yanayi na uku a cikin loop, yana iya a samu cewa potential a cikin yanayi na uku yana iya a bangarance da yanayi na hudu. Idan yake ci gaba a cikin closed loop, yake iya a samu cewa potential a cikin yanayi na uku yana iya a bangarance da yanayi na uku. Wannan tana iya a cewa net voltage gain da net voltage drops a cikin closed loop suna da shi. Wannan shine maimaita Kirchhoff Voltage law states. Wannan kananan al'adu tana kiran Kirchhoff Second Law.
Idan an kira closed loop a cikin convention, idan an kira duka voltage gains a cikin loop da positive, akwai convention da ke kira duka voltage drops a cikin loop da negative. Jumla duka waɗannan voltages a cikin closed loop tana iya a kira zero. Idan n numbers of back to back connected elements suna da closed loop. Daga waɗannan circuit elements, m number elements suna voltage source, kuma n – m number of elements suna drop voltage kamar resistors.
Voltages of sources are
And voltage drops across the resistors respectively,
Sannan cewa voltage gain a kira positive, kuma voltage drops a kira negative, voltages a cikin closed loop –
Duk da haka, a cikin Kirchhoff Voltage law, jumla duka waɗannan voltages tana iya a kira zero.
Saboda haka, a cikin Kirchhoff Second Law, ∑V = 0.
