Mụtakwa ihe atụ nke resistors ndị yiri ibe ha na ihe atụ nke resistors usoro.
Ihe Nguzogide Nlekota nke Parallel
Ọ bụrụ na e jikọtara resistors dịka ọ dị na foto dị n'akụkụ, resistors na-ejikọta n'otu oge.
A na-echekwa chajị ọkụ eletrik ka ọkụ eletrik (ọkụ eletrik = chajị ọkụ eletrik na-agba n'oge oge) na-abanye na ebe alaka ahụ wee bụrụ otu ihe ahụ ka ọkụ eletrik na-apụ na ebe alaka ahụ. E nwere ọtụtụ alaka ka ọkụ eletrik niile = mkpokọta nke ọkụ eletrik na-asọba na alaka ọ bụla. N'ụzọ mgbakọ na mwepụ I = I 1 + I 2 + I 3. Ọ bụ ezie na ọdịiche ike eletrik ma ọ bụ voltaji ọkụ eletrik (V) dị na alaka ọ bụla nwere otu uru.
I = V/R yabụ nha nhata dị n'elu na-agbanwe gaa na I = V/R 1 + V/R 2 + V/R 3. Voltaji eletriki ahụ bụ otu ihe ahụ ya mere nha nhata a na-agbanwe gaa na I = V (1/R 1 + 1/R 2 + 1/R 3 ). Ọ bụrụ na nguzogide nnọchi bụ 1/R mgbe ahụ I = V (1/R). Ya mere 1/R = 1/R 1 + 1/R 2 + 1/R 3.
Sekit parallel nwere uru na ọ bụrụ na e kwụsị ikpo ọkụ eletrik gaa na otu resistor, ọkụ eletrik na-aga n'ihu na-asọfe site na resistor ndị ọzọ. Na sekit usoro, ọ bụrụ na e kwụsị ikpo ọkụ eletrik gaa na otu resistor, resistor niile agaghị asọfe. Resistor nwere ike ịbụ bọlbụ ọkụ, ihe resistor, na ihe ndị ọzọ.
Ihe atụ nke ihe ndị na-eguzogide parallel:
1. E nyere R 1 = 2 Ω, R 2 = 3 Ω. Ejikọtara resistors abụọ ahụ n'otu nha. Gịnị bụ uru resistor nnọchi? (Ω = Ohm).
Mkparịta ụka
1/R = 1/R 1 + 1/R 2 = 1/2 + 1/3 = 3/6 + 2/6 = 5/6
R = 6/5 = 1,2 Ω.
Nsonaazụ a na-egosi na uru nguzogide nnọchi dị obere karịa uru nke nguzogide ọ bụla ejikọtara na parallel.
2. Ejikọtara resistors abụọ R 1 = 50 Ω na 50 Ω n'usoro na n'usoro, jikọọ na batrị 12 Volt. Chọpụta (a) nguzogide nhata (b) ọkụ eletrik na-agafe resistor ọ bụla.
Mkparịta ụka
(a)
Sekọnd usoro:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Sekit parallel:
1/R = 1/R 1 + 1/R 2 = 1/50 + 1/50 Ω = 2/50
R = 50/2 = 25 Ω
(B)
Sekọnd usoro:
I = V / R = 12 Volts / 100 Ω = 0,12 Amperes
Sekit parallel:
I = V / R = 12 Volts / 25 Ω = 0,48 Amperes
Nsonaazụ ndị a na-egosi na mkpokọta ọkụ eletrik na-asọfe na sekit parallel dị ukwuu, ebe mkpokọta ọkụ eletrik na-asọfe na sekit usoro dị obere.
