Ihe Nguzogide Usoro Ihe Nguzogide

Ọ bụrụ na e jikọtara resistors dịka egosiri na eserese dị n'elu, a na-ejikọ ha n'usoro. Resistors ndị a na-ekwu okwu ha nwere ike ịbụ ihe ndị na-egbochi resistors, oriọna, ma ọ bụ ngwaọrụ ndị ọzọ na-egbochi eletriki.

Ụgwọ ọkụ eletrik (Q) na-agbanwe agbanwe nke na chaja eletrik na-agafe nguzogide 1 (R)₁) = chaja eletrik na-agafe nguzogide 2 (R₂) = chaja eletrik na-agafe nguzogide 3 (R₃). Ọkụ eletrik (I) bụ chajị ọkụ eletrik nke na-asọ n'oge oge ụfọdụ (I = Q/t), ya mere ọkụ eletrik nke na-agafe n'iguzogide 1 (I₁) = ọkụ eletrik na-agafe nguzogide 2 (I₂) = ọkụ eletrik na-agafe nguzogide 3 (I₃). N'ime mgbakọ na mwepụ, mkpokọta ọkụ eletrik (I) = I₁ = M₂ = M₃.

Na ntụle voltaji eletriki (V) na-ebelata mgbe chaja eletrik na-agafe nguzogide ọ bụla. Voltaji eletriki, nke a na-akpọkwa ọdịiche ikike eletrik, bụ ike ike eletrik kwa nkeji nke chajị eletriki. Voltaji ahụ na-ebelata n'ihi na a na-eji ike eletriki eme ihe na nguzogide eletriki ọ bụla. Ya mere, voltaji eletriki dum (V) hà nhata na ngụkọta nke voltaji eletriki na nguzogide ọ bụla. N'ime mgbakọ na mwepụ, voltaji eletriki dum (V) = V₁ +V₂ +V₃V = IR yabụ ngụkọta voltaji eletriki bụ V = IR₁ + IR₂ + IR₃Ọkụ eletrik nke na-agafe n'ime resistor ọ bụla nwere otu uru ya mere nha nha a na-agbanwe gaa na V = I (R₁ + R₂ + R₃).

Dabere na nha anya dị n'elu, enwere ike ikwubi na nguzogide eletriki zuru oke (R) ma ọ bụ nguzogide nhata nke nguzogide eletriki ejikọtara na usoro bụ otu ihe ahụ dị ka ngụkọta nke nguzogide eletriki ọ bụla, n'ụzọ mgbakọ na mwepụ R = R₁ + R₂ + R₃Ọ bụrụ na e nwere naanị resistors abụọ ejikọtara na usoro, mgbe ahụ uru nke resistor nnọchi (R) = R₁ + R₂Ọ bụrụ na e nwere resistors anọ ejikọtara na usoro, mgbe ahụ uru nke resistor nnọchi (R) = R₁ + R₂ + R₃ + R₄N'otu aka ahụ, ọ bụrụ na e nwere ihe mgbochi ise ma ọ bụ karịa ejikọtara na usoro.

Ihe atụ nke nsogbu resistor usoro:

1. E nyere R₁ = 2Ω, R₂ = 3 Ω na R₃ = 4 Ω. Ejikọtara resistors atọ ahụ n'usoro. Gịnị bụ uru resistors nnọchi? (Ω = Ohm).

Mkparịta ụka

R=R₁ + R₂ + R₃ = 2 + 3 + 4 = 9 Ω.

Nsonaazụ a na-egosi na uru nguzogide nnọchi karịrị uru nguzogide nke nguzogide ọ bụla ejikọtara na usoro.

2. Resistors abụọ R₁ = 50 Ω na R₂ = 50 Ω ejikọtara n'usoro ma jikọọ na batrị 12 Volt. Chọpụta (a) nguzogide nhata (b) ọkụ eletrik na-agafe resistor ọ bụla.

Mkparịta ụka

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

(b) I = V / R = Volt 12 / 100 Ω = Ampere 0,12
