Sengoloa se buang ka Resistors ka nako e le 'ngoe
Haeba li-resistor li hokahane joalo ka setšoantšong, li-resistor li hokahane ka ho lekana.
Motlakase (motlakase = motlakase o phallang nakong ea nako) o kenang sebakeng sa kopano o tšoana le motlakase o tsoang sebakeng sa kopano. Ho na le libaka tse 'maloa tsa kopano e le hore motlakase oohle = palo ea motlakase o phallang sebakeng se seng le se seng sa kopano. Ho ea ka lipalo, I = I 1 + I 2 + I 3 . Leha phapang ea matla a motlakase kapa motlakase sebakeng se seng le se seng sa kopano e tšoana.
I = V/R kahoo equation e kaholimo e fetoha ho I = V/R 1 + V/R 2 + V/R 3 . Motlakase oa motlakase o lekana, kahoo equation ena e fetoha ho I = V (1/R 1 + 1/R 2 + 1/R 3 ). Haeba khanyetso e lekanang e le 1/R joale I = V (1/R). Kahoo, 1/R = 1/R 1 + 1/R 2 + 1/R 3.
Dipotoloho tse bapileng di na le molemo, haeba motlakase o kenang ho e nngwe ya di-resistor o robehile, motlakase o tswela pele ho phalla ho di-resistor tse ding. Athe ka tatellano, haeba motlakase o kenang ho resistor e le nngwe o robehile, di-resistor tsohle di ke ke tsa fuwa motlakase.
Bothata ba mohlala oa 1:
Ho tsebahala hore R 1 = 2 Ω, R 2 = 3 Ω. Li-resistor ka bobeli li bapile. Boleng ba resistor e lekanang ke bofe? (Ω = Ohm).
tharollo:
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 bo lekanang ba resistor bo bonyenyane ho feta boleng ba resistor ka 'ngoe e bapileng.
Bothata ba mohlala oa 2:
Li-resistor tse peli tsa R 1 = 50 Ω le 50 li hokahane ka tatellano le ka tsela e ts'oanang, li hokahantsoe le betri ea 12 Volt. Fumana:
(a) Khanyetso e lekanang
(b) Motlakase o fetang ka har'a resistor ka 'ngoe
tharollo:
(a) Li-resistor ka letoto:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Li-resistor tse tšoanang:
1/R = 1/R 1 + 1/R 2 = 1/50 + 1/50 Ω = 2/50
R = 50/2 = 25 Ω
(b) Li-resistor ka letoto:
I = V / R = 12 Volts / 100 Ω = 0.12 A
Li-resistor tse tšoanang:
I = V / R = 12 Volts / 25 Ω = 0.48 A
Sephetho sena se bontša hore motlakase o phallang ka kakaretso potolohong e bapileng o moholo, ha motlakase o phallang ka kakaretso letotong o le monyane.
