Mene ne serial dangane?

Series dangane - shi ne a fili a cikin abin da abubuwa suna da alaka ne kawai a daya karshen. A jerin ne halin a cewa shi zame wani sashe.

A jerin dangane da layi daya halin a cewa an yi shi a cikin wani layi daya connection, wanda ya kamata a kalla biyu nodes.

Resistors - Waɗannan su ne abubuwa na wucin gadi juriya. Suna amfani da lantarki a matsayin ƙarin kaya don rage ƙarfin lantarki ko halin yanzu kewaye. Ta yaya wannan ne yake aikata?

Idan dole don rage halin yanzu, shi ne sanya jerin dangane da resistors. A wannan yanayin, yanzu juriya kowane ne guda, kuma da m bambanci ne daban-daban. Ya kamata a lura da cewa yuwuwar bambancin - wato, da girma da irin ƙarfin lantarki maniyyi, shi ya dogara da juriya na resistor.

Alal misali, a wani rangadi da wani irin ƙarfin lantarki na 220 V ne nada juriya ne 1 ohm. Idan ɗaya daga cikin gẽfe guda biyu don sallama lokaci, da kuma na biyu - sifili, a gaskiya akwai zai zama wani gajeren kewaye, don haka kamar yadda 1 ohm - yana da ma kadan. Akwai zai zama wata babbar halin yanzu, da nada zai ƙone, kuma doke fitar da cibiyar sadarwa. Idan nada a jerin to sa biyu resistors 500 ohms, da gajeren kewaye ba, da kuma nada zai yi aiki kamar yadda ya kamata.

A layi daya dangane da kowane reshe igiyoyin zai bambanta, amma ƙarfin lantarki zai zama guda. Saboda haka, yanzu darajar kowane sashi dogara a kan juriya na wannan sashi. Wannan makirci da ake amfani da su kara da irin ƙarfin lantarki drop. Alal misali, da juriya na nada aka tsara don 50 B. Don a kunna wannan cibiyar sadarwa zuwa 220, dole ne su kasance a layi daya ya sadar dace juriya. A da shi za su haifar da wani irin ƙarfin lantarki maniyyi, da kuma nada ba zai ƙone.

Saboda haka, a layi daya da serial connection ake amfani da su a lokuta na musamman da kuma aiki daidai da Ohm ta dokar.

Idan da za'ayi a jerin dangane da LEDs, shi wajibi ne mu tuna cewa a cikin hali na gazawar da a kalla daya daga cikinsu zai kashe dukan sarkar. Kamar yadda aka ambata riga, yanzu daya a wurin breakage zargin kwarara aka tsaya da kewaye ne karye. Idan aka haɗa a layi daya, shi ba kome wanda ya jagoranci ne m, da sauran za su ci gaba da sale.

Idan jerin juriya da yin amfani da wannan ƙungiyõyi resistors, jimlar adadin shi ne daidaita da samfurin na wani juriya da jimlar yawan abubuwa.

Idan resistor dabi'u ne daban-daban, sa'an nan jimlar juriya ne daidai da Naira Miliyan Xari da resistances na kowane kashi.

Idan aka haɗa a layi daya count gudanar da ɗan daban. Alal misali, akwai wani jerin uku ƙungiyõyi resistances R1, R2, R3. Don samun jimlar juriya da kewaye a layi daya dangane, shi wajibi ne yin lissafi da Naira Miliyan Xari da reciprocals na dabi'u na wadannan ƙungiyõyi, folded Ina nufin uku kasarun adadi 1 / R1 + 1 / R2 + 1 / R3. Kasarun adadi an rage wa mai hada - da kuma lasafta sakamakon. A sakamakon sulusi da murabba'i ne inverted kuma an dauki karshe darajar.

Domin karba da juriya ga wani rangadi, shi ne wajibi ne don yin lissafin daidai. Wasu masana kokarin karba resistors da gwaje-gwajen. Duk da haka, ko da a wannan yanayin, a kalla wajen sanin wanda resistor dabi'u iya zama mafi kyau duka.
