Lipotoloho tsa motlakase tse nang le li-resistor tse hanyetsanang le tsa kahare - mathata le litharollo

1. Ho latela setšoantšo se ka tlase, haeba mohloli oa matla a motlakase (emf) e le 24 Volts, fumana motlakase oa motlakase I.

Tse tsejoang:

Mohloli oa emf = 24 Volt

Khanyetso ea ka hare (r) = 2 Ohms

Li-resistor tsa 40 Ohm, 20 Ohm, le 20 Ohm.

Wante d: Motlakase oa motlakase I

Tharollo:

Li-resistor tse hokahantsoeng ka ho lekana, resistor e lekanang:

1/R = 1/40 + 1/20 + 1/20

1/R = 1/40 + 2/40 + 2/40

1/R = 5/40

R = 40/5

R = 8 Ohm

Motlakase oa seteishene:

V = emf – I r

V = 24 – I 2

Motlakase oa motlakase oa I:

V = IR

24 – Ke 2 = Ke 8

24 = Ke 8 + Ke 2

24 = Ke (10)

Ke = 24/10

I = 2.4 Ampere

2. Ho latela setshwantsho se ka tlase, haeba R ₁ = 3 Ω, R ₂ = 4 Ω, R ₃ = 4 Ω mme motlakase wa motlakase ke 0.5 A. Fumana motlakase wa motlakase.

Tse tsejoang:

Motlakase oa motlakase (I) = 0.5 Ampere

Mohanyetsi R ₁ = 3 Ohm

Mohanyetsi R ₂ = 4 Ohm

Mohanyetsi R ₃ = 4 Ohm

Ho batloa: Motlakase oa motlakase (V)

Tharollo:

Bala khanyetso e lekanang:

R2 le R3 _li hokahane ka ho bapa. Resistor e lekanang _:

1 /R ₂₃ = 1/R ₂ + 1/R ₃ = 1/4 + 1/4 = 2/4

R ₂₃ = 4/2 = 2 Ohm

R ₁ le R ₂₃ li hokahane ka letoto. Resistor e lekanang:

R = R ₁ + R ₂₃ = 3 + 2 = 5 Ohms

Motlakase oa motlakase:

V = IR = (0.5)(5) = 2.5 Volt
