Ma resistors ane resistance value inoyerwa mu ohms (Ω). Resistance iyi inogona kuverengwa uchishandisa color code iri pa resistor body. Pamusoro pezvo, ma resistors anewo power rating, inoburitswa mu watts (W), zvichiratidza kuti resistor inogona kuburitsa simba rakawanda sei pasina kukuvara.
Kune mhando dzakasiyana-siyana dzemasekete anowanzo shandiswa munyika yemagetsi, kusanganisira masekete akatevedzana uye akaenzana. Kunzwisisa maitiro ekuverenga resistance yese mumasekete akasiyana kwakakosha kune avo vanoshanda nemagetsi.
Mibvunzo yemuenzaniso nekukurukurirana
Muenzaniso Mubvunzo 1: Dunhu reNhevedzano
Mubvunzo: Kune ma resistors matatu ane kukosha kwe100 Ω, 200 Ω, uye 300 Ω akabatana akatevedzana. Ndeipi resistance yese yedunhu?
Kukurukurirana:
Muchikamu cheseti, resistance yese (R_total) ndiyo huwandu hwe resistance dzese dzega dzega.
"`Chinyorwa chakajeka
R_huwandu = R1 + R2 + R3
``
Isa ma resistor values mu equation:
"`Chinyorwa chakajeka
R_total = 100 Ω + 200 Ω + 300 Ω
= 600 Ω
``
Saka, kupokana kwese kwedunhu i600 Ω.
Muenzaniso Mubvunzo 2: Parallel Circuit
Mubvunzo: Kune ma resistors matatu ane kukosha kwe100 Ω, 200 Ω, uye 300 Ω akabatana zvakafanana. Ndeipi resistance yese yedunhu?
Kukurukurirana:
Muchikamu chinotenderera zvakafanana, inverse ye total resistance (1/R_total) ihuwandu hwe inverses ye all individual resistances.
"`Chinyorwa chakajeka
1/R_huwandu = 1/R1 + 1/R2 + 1/R3

Isa ma resistor values mu equation:
"`Chinyorwa chakajeka
1/R_total = 1/100 Ω + 1/200 Ω + 1/300 Ω
1/R_huwandu = 0.01 + 0.005 + 0.00333
1/R_huwandu = 0.01833
``
Kuti uwane kuramba kwakakwana, tora zvinopesana nehuwandu:
"`Chinyorwa chakajeka
R_total = 1 / 0.01833 ≈ 54.55 Ω
``
Saka, kupokana kwese kwedunhu iri kunenge 54.55 Ω.
Muenzaniso Dambudziko 3: Mixed Circuits
Mubvunzo: Kune ma resistors matatu R1 = 150 Ω, R2 = 100 Ω, uye R3 = 50 Ω. Ma resistors R1 naR2 akabatana akatevedzana, ozobatanidzwa pamwe chete ne resistor R3. Ndeipi resistance yese yecircuit?
Kukurukurirana:
Kutanga, verenga kuramba kweR1 neR2 zvakabatana munhevedzano:
"`Chinyorwa chakajeka
R_serie = R1 + R2 = 150 Ω + 100 Ω = 250 Ω
``
Wobva wabatanidza mhedzisiro yacho pamwe chete neR3:
"`Chinyorwa chakajeka
1/R_huwandu = 1/R_series + 1/R3
1/R_total = 1/250 Ω + 1/50 Ω
1/R_huwandu = 0.004 + 0.02
1/R_huwandu = 0.024
``
Tora zvinopesana nehuwandu ihwohwo kuti uwane kuramba kwakakwana:
"`Chinyorwa chakajeka
R_total = 1 / 0.024 ≈ 41.67 Ω
``
Saka, kupokana kwese kwedunhu iri kunenge 41.67 Ω.
Muenzaniso Mubvunzo 4: Mhedzisiro yeVoltage neCurrent
Mubvunzo: Resistor ine kukosha kwe120 Ω yakabatana nesosi yevoltage ye12 V. Ingani magetsi ari kufamba nemu resistor?
Kukurukurirana:
Shandisa mutemo weOhm kuti uwane simba remagetsi (I) richiyerera nemuchina unorwisa mafungu. Mutemo weOhm unoti:
"`Chinyorwa chakajeka
V = IR
``
Apo V iri voltage, I iri current, uye R iri resistance. Kuti uwane current, fomura inogona kuchinjwa kuita:
"`Chinyorwa chakajeka
Ini = V / R
``
Tsiva tsika dzinozivikanwa:
"`Chinyorwa chakajeka
I = 12 V / 120 Ω
= 0.1A

Saka, simba remagetsi rinoyerera nepakati pe resistor i0.1 A kana 100 mA.
Muenzaniso Mubvunzo 5: Kurasikirwa Nesimba MuResistor
Mubvunzo: Resistor ye50 Ω inopfuudzwa nemagetsi e2 A. Simba rakawanda sei rinorasika mu resistor?
Kukurukurirana:
Simba rinorasika mu resistor rinogona kuverengwa uchishandisa fomura:
"`Chinyorwa chakajeka
P = I^2 R
``
Apo P iri simba, I iri simba remagetsi, uye R iri simba rekudzivirira. Tsiva maitiro anozivikanwa:
"`Chinyorwa chakajeka
P = (2 A)^2 50 Ω
= 4 50
= 200W
``
Saka, simba rinorasika mu resistor i200 W.
Muenzaniso Dambudziko 6: Kusanganiswa kweDunhu
Mubvunzo: Mudunhu, mune ma resistors mana ane kukosha kweR1 = 100 Ω, R2 = 50 Ω, R3 = 300 Ω, uye R4 = 200 Ω. R1 naR2 zvakabatana munhevedzano, ipapo mhedzisiro yacho yakabatana munhevedzano neR3. Tevere, mhedzisiro yemusanganiswa wekare yakabatana munhevedzano neR4. Ndeipi resistance yese yedunhu?
Kukurukurirana:
Kutanga, verenga kuramba kweR1 neR2 zvakabatana munhevedzano:
"`Chinyorwa chakajeka
R_12 = R1 + R2 = 100 Ω + 50 Ω = 150 Ω
``
Wobva wabatanidza mhedzisiro yacho pamwe chete neR3:
"`Chinyorwa chakajeka
1/R_123 = 1/R_12 + 1/R3
1/R_123 = 1/150 Ω + 1/300 Ω
1/R_123 = 0.00667 + 0.00333
1/R_123 = 0.01
``
Tora zvinopesana nehuwandu uhwu kuti uwane resistance R_123:
"`Chinyorwa chakajeka
R_123 = 1 / 0.01 = 100 Ω
