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.
Ishaja kagesi igcinwa ukuze ugesi kagesi (ugesi kagesi = ishaja kagesi egeleza ngesikhathi esithile) engena endaweni yegatsha ifane nogesi kagesi ophuma endaweni yegatsha. Kunezinhlobo eziningana zamagatsha ukuze ugesi ophelele = isamba semisinga kagesi egeleza egatsheni ngalinye. Ngokwezibalo I = I 1 + I 2 + I 3 . Ngenkathi umehluko wamandla kagesi noma i-voltage kagesi (V) egatsheni ngalinye inenani elifanayo.

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.
