Lisebelisoa tsa Resistor tse Tšoanang
Haeba li-resistor li hokahane joalo ka setšoantšong se ka lehlakoreng, li-resistor li hokahane ka ho lekana.
Tefiso ea motlakase e bolokoa e le hore motlakase (motlakase oa motlakase = tjhaja ea motlakase e phallang nakong ea nako) e kenang ntlheng ea lekala e tšoane le motlakase o tlohang ntlheng ea lekala. Ho na le makala a 'maloa e le hore motlakase oohle = kakaretso ea maqhubu a motlakase a phallang lekaleng ka leng. Ho latela lipalo I = I 1 + I 2 + I 3 . Leha phapang ea matla a motlakase kapa motlakase oa motlakase (V) lekaleng ka leng e na le boleng bo tšoanang.
I = V/R kahoo equation e kaholimo e fetoha ho I = V/R 1 + V/R 2 + V/R 3 . Motlakase oa motlakase o ts'oana kahoo equation ena e fetoha ho I = V (1/R 1 + 1/R 2 + 1/R 3 ). Haeba khanyetso e nkeloang sebaka e le 1/R joale I = V (1/R). Kahoo 1/R = 1/R 1 + 1/R 2 + 1/R 3.
Potoloho e bapileng e na le molemo oa hore haeba hona joale ho ea ho resistor e 'ngoe ho sitisoa, hona joale ho tsoela pele ho phalla ka har'a resistor tse ling. Potolohong ea letoto, haeba hona joale ho ea ho resistor e 'ngoe ho sitisoa, resistor tsohle li ke ke tsa phalla. Resistor e ka ba mabone a mabone, likarolo tsa resistor, le likarolo tse ling.
Mohlala oa li-resistor tse bapileng:
1. Ha ho fanoe ka R 1 = 2 Ω, R 2 = 3 Ω. Li-resistor ka bobeli li hokahane ka ho lekana. Boleng ba resistor e nkelang sebaka ke bofe? (Ω = Ohm).
Puisano
1/R = 1/R 1 + 1/R 2 = 1/2 + 1/3 = 3/6 + 2/6 = 5/6
R = 6/5 = 1,2 Ω.
Sephetho sena se bontša hore boleng ba khanyetso ea ho nkela sebaka bo bonyenyane ho feta boleng ba khanyetso ka 'ngoe e hokahantsoeng ka nako e le 'ngoe.
2. Li-resistor tse peli R 1 = 50 Ω le 50 Ω li hokahane ka tatellano le ka tsela e ts'oanang, li hokahane le betri ea 12 Volt. Fumana (a) khanyetso e lekanang (b) motlakase o fetang ka har'a resistor ka 'ngoe.
Puisano
(A)
Potoloho ea letoto:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Potoloho e bapileng:
1/R = 1/R 1 + 1/R 2 = 1/50 + 1/50 Ω = 2/50
R = 50/2 = 25 Ω
(B)
Potoloho ea letoto:
Ke = V / R = 12 Volts / 100 Ω = 0,12 Ampere
Potoloho e bapileng:
Ke = V / R = 12 Volts / 25 Ω = 0,48 Ampere
Liphetho tsena li bontša hore motlakase oohle o phallang potolohong e bapileng o moholo, ha motlakase oohle o phallang potolohong e latellanang o le monyane.
