Cov Khoom Siv Resistance Series

Yog tias cov resistors txuas nrog raws li qhia hauv daim duab saum toj no, lawv txuas ua ke. Cov resistors hauv nqe lus nug tuaj yeem yog cov khoom siv resistor, teeb, lossis lwm yam khoom siv hluav taws xob rwb thaiv tsev.

Lub zog hluav taws xob (Q) yog qhov tsis hloov pauv kom lub zog hluav taws xob txav mus los ntawm qhov tsis kam 1 (R)₁) = lub zog hluav taws xob txav mus los ntawm qhov tsis kam 2 (R₂) = lub zog hluav taws xob txav mus los ntawm qhov tsis kam 3 (R₃). Tam sim no hluav taws xob (Kuv) yog lub nqi hluav taws xob uas ntws thaum lub sijhawm tshwj xeeb (Kuv = Q/t), yog li ntawd, lub zog hluav taws xob uas hla dhau qhov tsis kam 1 (Kuv₁) = hluav taws xob tam sim no hla dhau qhov tsis kam 2 (I₂) = hluav taws xob tam sim no hla dhau qhov tsis kam 3 (I₃). Kev suav lej, tag nrho cov hluav taws xob tam sim no (I) = Kuv₁ = Kuv₂ = Kuv₃.

Ntawm qhov tsis sib xws hluav taws xob voltage (V) txo qis thaum lub zog hluav taws xob txav mus los ntawm txhua qhov tsis kam. Lub zog hluav taws xob, tseem hu ua qhov sib txawv ntawm lub zog hluav taws xob, yog lub zog hluav taws xob ib chav ntawm cov nqi hluav taws xob. Qhov hluav taws xob txo qis vim tias lub zog hluav taws xob siv rau hauv txhua qhov kev tiv thaiv hluav taws xob. Yog li tag nrho cov hluav taws xob hluav taws xob (V) yog sib npaug rau qhov sib npaug ntawm cov hluav taws xob hluav taws xob ntawm txhua qhov kev tiv thaiv. Kev suav lej, tag nrho cov hluav taws xob hluav taws xob (V) = V₁ +V₂ +V₃. V = IR yog li ntawd tag nrho cov hluav taws xob voltage equation yog V = IR₁ + IR₂ + IR₃Cov hluav taws xob uas ntws los ntawm txhua lub resistor muaj tib tus nqi yog li cov kab zauv no hloov mus rau V = I (R₁ + R₂ + R₃).

Raws li qhov sib npaug saum toj no, nws tuaj yeem xaus lus tias tag nrho cov hluav taws xob tsis kam (R) lossis qhov sib npaug ntawm cov hluav taws xob tsis kam txuas nrog hauv series yog tib yam li qhov sib npaug ntawm txhua qhov hluav taws xob tsis kam, lej R = R₁ + R₂ + R₃Yog tias tsuas muaj ob lub resistors txuas ua ke, ces tus nqi ntawm lub resistor hloov (R) = R₁ + R₂Yog tias muaj plaub lub resistors txuas ua ke ces tus nqi ntawm lub resistor hloov (R) = R₁ + R₂ + R₃ + R₄Ib yam li ntawd, yog tias muaj tsib lossis ntau dua resistors txuas nrog hauv series.

Piv txwv ntawm qhov teeb meem ntawm series resistor:

1. Muab R₁ = 2 Ω, R₂ = 3 Ω thiab R₃ = 4 Ω. Peb lub resistors txuas ua ke. Tus nqi ntawm lub resistor hloov pauv yog dab tsi? (Ω = Ohm).

Kev Sib Tham

R = R₁ + R₂ + R₃ = 2 + 3 + 4 = 9 Ω.

Qhov tshwm sim no qhia tau hais tias tus nqi tiv thaiv hloov pauv loj dua tus nqi tiv thaiv ntawm txhua lub resistor txuas nrog hauv series.

2. Ob lub resistors R₁ = 50 Ω thiab R₂ = 50 Ω txuas ua ke thiab txuas rau lub roj teeb 12 Volt. Txheeb xyuas (a) qhov sib npaug ntawm qhov tsis kam (b) qhov hluav taws xob uas hla dhau txhua lub resistor.

Kev Sib Tham

(a) R = R₁ + R₂ = 50 Ω + 50 Ω = 100 Ω.

(b) Kuv = V / R = 12 Volts / 100 Ω = 0,12 Ampere
