Funda futhi izibonelo zama-resistor ahambisanayo kanye nezibonelo zama-resistor alandelanayo.
Izinto Zokumelana Nokumelana Ezihambisanayo
Uma ama-resistor exhunywe njengasesithombeni ohlangothini, ama-resistor axhunywe ngokuhambisana.
Ukushaja kukagesi okuphakade ukuze ugesi wamanje (ugesi wamanje = ukushaja kukagesi okugeleza ngesikhathi sokuphumula) okungena endaweni yegatsha kufana nogesi ophuma endaweni yegatsha. Kunezinhlobo eziningana zamagatsha ukuze ugesi ophelele = isamba semithombo kagesi egeleza egatsheni ngalinye. Ngokwezibalo I = I1 + Mina2 + Mina3. Nakuba umehluko wamandla kagesi noma i-voltage kagesi (V) egatsheni ngalinye inenani elifanayo.
Funda futhi izibonelo zama-resistor ahambisanayo kanye nezibonelo zama-resistor alandelanayo.
Izinto Zokumelana Nokuphikisa Uchungechunge
Uma ama-resistor exhunywe njengoba kuboniswe kumdwebo ongenhla, axhunywe ngokulandelana. Ama-resistor okukhulunywa ngawo angaba izingxenye zama-resistor, izibani, noma amanye amadivayisi kagesi okuvikela.
Ishaja kagesi (Q) ayiguquguquki ukuze ishaja kagesi ehamba ngokumelana 1 (R1 ) = ishaja kagesi ehamba ngokumelana 2 (R2 ) = ishaja kagesi ehamba ngokumelana 3 (R3 ) . Ugesi wamanje (I) yishaja kagesi egeleza phakathi nesikhathi esithile (I = Q/t), ngakho-ke ugesi odlula ngokumelana 1 (I1 ) = ugesi odlula ngokumelana 2 (I2 ) = ugesi odlula ngokumelana 3 (I3 ) . Ngokwezibalo, ugesi ophelele (I) = I 1 = I 2 = I 3.
Wake wazibuza ukuthi kungani amafu ehlala phezulu futhi ehla ezintabeni noma emagqumeni ngesikhathi semvula? Lapho kufika isikhathi semvula, amafu angehla ngisho nasezintabeni noma emagqumeni bese ebuyela phezulu. Kungani amafu ehla, futhi yini ebangela ukuba akhuphukele phezulu futhi?
Ukuze uqonde lokhu, qala uqonde umqondo wobuningi . Ubuningi buyisilinganiso sobuningi nobuningi, esivezwa ngokwezibalo nge-equation ρ = m / V, lapho u-ρ ewuphawu lobuningi, u-m uwuphawu lobuningi kanti u-V uwuphawu lobuningi. Isibonelo, uma isisindo = 1 kg kanye nomthamo = 1 m 3 khona-ke ubuningi = 1/1 = 1 kg / m 3. Uma isisindo = 1 kg kanye nomthamo = 2 m 3 khona-ke ubuningi = 1/2 = 0,5 kg / m 3. Ngokufanayo, uma isisindo = 1 kg kanye nomthamo = 4 m 3 khona-ke ubuningi = 1/4 = 0,25 kg / m 3. Kungaphethwa ngokuthi uma ivolumu ikhuphuka kuyilapho ubuningi buhlala bunjalo khona-ke ubuningi buyancipha.
Amandla, njengoba kufundwe esigabeni somsebenzi namandla , achazwa njengomsebenzi owenziwe esikhathini esithile. Umsebenzi inqubo yokuguqulwa kwamandla, ngakho amandla angaqondwa njengoshintsho lwamandla esikhathini esithile.
Amandla kagesi ushintsho lwamandla kagesi phakathi nesikhathi esithile. Ingxoxo mayelana namandla kagesi ichaza ukuthi izinguquko zamandla kagesi ezenzeka lapho ishaja kagesi idlula umehluko wamandla kagesi.
I-resistor iyisici sesekethe kagesi esisebenza ukulawula usayizi wamandla kagesi. ugesi wamanjeAma-resistor asetshenziswa kumasekethe kagesi ngokuvamile anesiyingi esinocingo kuzo zombili izinhlangothi. Inani lokumelana le-resistor liboniswa ikhodi yombala futhi liboniswa ebusweni be-resistor.
Inani lokumelana le-resistor lingaziwa ngokuhumusha ikhodi yombala yokumelanaUkuze uqonde lokhu, qala uhlole ithebula elilandelayo, bese ufunda isibonelo senkinga yokunquma inani lokumelana le-resistor.
