Isixazululo Ngokusho komfanekiso ongenhla, izakhiwo zesithombe zingokoqobo, ziqondile futhi zinkulu kunento. 2. Uma into ibekwe ku- … Funda kabanzi

I-transformer yesinyathelo phezulu nesinyathelo phansi – izinkinga nezixazululo 1. I-transformer ine-coil eyinhloko kanye ne-coil yesibili enenani lama-loops angu-500 no-5000. I-voltage yokufaka ingu-220 V. Iyini i-voltage yokuphuma? Eyaziwayo: I-coil eyinhloko (NP) = ama-loops angu-500 I-coil yesibili (Ns) = ama-loops angu-5000 I-voltage eyinhloko (VP) … Funda kabanzi

Ukucindezela kwezinto eziqinile - izinkinga nezixazululo 1. Isisindo kanye nomthamo wamabhulokhi amane ngezansi kuyafana. Yikuphi ukucindezela okuncane okukhishwa yibhulokhi phansi? Isixazululo P = F / A Ngokusekelwe kule fomula kuphethwe ngokuthi ukucindezela (P) kuhambelana ngqo namandla (F) futhi kuhambelana ngokuphambene nobuso … Funda kabanzi

Amasekethe e-Resistors – izinkinga nezixazululo 1. Yisiphi isekethe se-resistors, njengoba kuboniswe esithombeni esingezansi, esinokumelana okukhulu. Impendulo A R1 = 2 Ω, R2 = 2 Ω, R3 = 6 Ω, R4 = 6 Ω R3 kanye ne-R4 zixhunywe ngokulingana. I-resistor efanayo: 1/R34 = 1/R3 + … Funda kabanzi

Amasekethe kagesi – izinkinga nezixazululo 1. R1, = 6 Ω, R2 = R3 = 2 Ω, kanye ne-voltage = 14 volts, kunqunywa ugesi osesekethe njengoba kuboniswe esithombeni esingezansi. Kwaziwa: I-Resistor 1 (R1) = 6 Ω I-Resistor 2 (R2) = 2 Ω I-Resistor 3 (R3) = 2 Ω I-Voltage (V) … Funda kabanzi

Ukushisa nokushintsha kwesigaba - izinkinga nezixazululo 1. Ngokusekelwe kugrafu, yikuphi ukushisa okumuncwa amanzi angu-5-kg ngesikhathi senqubo ye-CD? Ukushisa okuqondile kwamanzi = 4,200 J/kg oC. Kwaziwa: Isisindo (m) = 5 kg Ukushisa okuqondile kwamanzi (c) = 4200 J/kg oC Ukushisa kokuqala (T1) = 0 … Funda kabanzi
