Isiokwu gbasara Resistors n'usoro
Ọ bụrụ na njikọ resistors dịka egosiri na eserese ahụ, a na-ahazi resistors n'usoro. Resistor ma ọ bụ eletriki resistance dị na ajụjụ a nwere ike ịbụ n'ụdị ihe resistor, ọkụ, ma ọ bụ eletriki resistance ndị ọzọ.
Chajị eletriki na-agafe n'usoro iguzogide 1 (R)1) = ihe ọkụ eletrik na-agafe nguzogide 2 (R)2) = chaja eletrik na-agagharị site na nguzogide 3 (R3). Ọkụ eletrik (I) bụ chaja eletriki nke na-agba n'oge oge ụfọdụ (I = Q / t), ya mere ọkụ eletrik ahụ na-agba site na iguzogide 1 (I1) = ọkụ eletrik site na iguzogide 2 (I2) = ọkụ eletrik site na iguzogide 3 (I3). N'ime mgbakọ na mwepụ, mkpokọta ọkụ eletrik (I) = I1 = M2 = M3.
N'aka nke ọzọ, voltaji eletrik (V) na-ebelata mgbe chajị eletrik na-agafe na resistor ọ bụla. Voltaji eletrik a na-akpọkwa ọdịiche ikike eletrik, bụ ike ikike eletrik kwa nkeji nke chajị eletrik. A na-ebelata voltaji eletrik n'ihi na a na-eji ọkụ eletrik eme ihe na nguzogide eletriki ọ bụla. Ya mere, voltaji eletrik dum (V) hà nhata ọnụọgụ ọkụ eletrik dị na resistor ọ bụla. N'ime mgbakọ na mwepụ, voltaji eletrik dum (V) = V1 +V2 +V3V = IR yabụ nha nha nke voltaji eletrik bụ V = IR1 + IR2 + IR3Ọkụ eletrik nke na-asọ na resistor ọ bụla hà nhata nke mere na nha nhata a ga-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
nke ejikọtara na usoro hà nhata na ngụkọta nke nguzogide eletriki ọ bụla, n'ụzọ mgbakọ na mwepụ R = R1 + R2 + R3Ọ bụrụ na e nwere naanị resistors abụọ n'usoro, resistor nhata (R) = R1 + R2Ọ bụrụ na e nwere ihe mgbochi anọ n'usoro, ihe mgbochi nhata (R) = R1 + R2 + R3 + R4N'otu aka ahụ, ọ bụrụ na e nwere ihe mgbochi ise ma ọ bụ karịa ise ejikọtara na usoro.
Ihe atụ nke nsogbu nke abụọ:
Ọ bụrụ na a maara ya, R 1 = 2 Ω, R 2 = 3 Ω na R 3 = 4 Ω. A na-ejikọ resistors atọ niile n'usoro. Gịnị bụ uru nke resistor nhata? (Ω = Ohm ).
ngwọta:
R = R 1 + R 2 + R 3 = 2 + 3 + 4 = 9 Ω.
Nsonaazụ a na-egosi na nguzogide nhata ahụ karịrị uru nke nguzogide ejikọtara na usoro.
Ihe atụ nke nsogbu nke abụọ:
A na-ejikọ resistors abụọ R 1 = 50 Ω na 50 Ω n'usoro ma jikọọ na batrị 12 Volt. Chọpụta
(a) Nguzogide nhata ahụ
(b) Ọkụ eletrik site na resistor ọ bụla
ngwọta:
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = Volt 12 / 100 Ω = 0.12 A
