Li-EMF tse latellanang le tse bapileng
Haeba ho na le mehloli e 'meli kapa ho feta ea electromotive (emf) e hokahaneng joalo ka ha ho bontšitsoe setšoantšong, emf e hlophisitsoe ka tatellano.
Mohloli o lekanang oa motlakase (ε) ke:
ε = ε 1 + ε 2 + ε n
Khanyetso e lekanang ea kahare (r) ke:
r = r 1 + r 2 + r n
Motlakase o phallang ka khanyetso ea kantle (R) ke:
Ke = ε / (r + R)
Bothata ba mohlala:
A re re libeteri tse peli tsa emf ka 'ngoe ke 1.5 Volt 'me boleng ba khanyetso ea kahare ho betri ka 'ngoe ke 0.1 Ω. Khanyetso ea kantle (R) = 10 Ω. Tsela ea motlakase oa motlakase ho ea ka oache.
Sebelisa foromo e fetileng:
ε = 1.5 + 1.5 = 3 Volt
r = 0.1 + 0.1 = 0.2 Ω
Ke = ε / (r + R) = 3 / (0.2 + 10)
Ke = 3 / 10.2
Ke = 0.294 A
Sebelisa molao oa bobeli oa Kirchhoff:
1.5 – 0.1 I + 1.5 – 0.1 I – 10 I = 0
3 – 0.2 I – 10 I = 0
3 – 10.2 I = 0
3 = 10.2 I
Ke = 3 / 10.2
Ke = 0.294 A
Haeba ho na le mehloli e 'meli kapa ho feta ea electromotive (emf) e hokahaneng joalo ka ha ho bontšitsoe setšoantšong, emf e hokahantsoe ka ho lekana.
Mohloli o lekanang oa motlakase (ε) ke:
ε = ε1 = ε2 = εn
Khanyetso e lekanang ea kahare (r) ke:
1/r = 1/r 1 + 1/r 2 + 1/r n
Motlakase o phallang ka khanyetso ea kantle (R) ke:
Ke = ε / (r + R)
Bothata ba mohlala:
A re re libeteri tse peli tsa emf ka 'ngoe ke 1.5 Volt 'me boleng ba khanyetso betring ka 'ngoe ke 0.1 Ω. Khanyetso ea kantle (R) = 10 Ω.
Sebelisa foromo e fetileng:
ε = 1.5 Volt
1/r = 1/0.1 + 1/0.1 = 2 / 0.1
r = 0.1 / 2 = 0.05 Ω
Ke = ε / (r + R) = 1.5 / (0.05 + 10) = 1.5 / 10.05
Ke = 0.149 A
Sebelisa molao oa Kirchhoff
Sebelisa molao oa pele oa Kirchhoff :
Ke 1 + Ke 2 = Ke ……. Tekanyo 1
Sekaseka sekotwana sa Aefca. Tsela eo sekotwana se tsamayang ka yona e ya ka watjhe. Sebedisa molao wa bobedi wa Kirchhoff:
ε 2 – I 1 r 2 – IR = 0
1.5 – 0.1 I 1 – 10 I = 0
– 0.1 I 1 = 10 I – 1.5
Ke 1 = (10 Ke – 1.5) / – 0.1
I 1 = -100 I + 15 ………. Tekanyo 2
Sekaseka sekotwana sa Befdb. Tsela eo sekotwana se tsamayang ka yona e ya ka watjhe. Sebedisa molao wa bobedi wa Kirchhoff:
ε 1 – I 2 r 1 – IR = 0
1.5 – 0.1 I 2 – 10 I = 0
– 0.1 I 2 = 10 I – 1.5
Ke 2 = (10 Ke – 1.5) / – 0.1
I 2 = -100 I + 15 ………. Tekanyo 3
Kenya diekate tsa 2 le 3 sebakeng sa ekate ya 1:
Ke 1 + Ke 2 = Ke
-100 I + 15 – 100 I + 15 = I
– 200 I + 30 = I
30 = Ke + 200 Ke
30 = 201 I
Ke = 30 / 201
Ke = 0.149 A
Tlosa equation ea 2 le ea 3:
1 1 = -100 1 + 15
1 2 = -100 1 + 15
——————– –
Ke 1 – Ke 2 = 0
Ke 1 = Ke 2 ………. Tekanyo ea 4
Hobane ke 1 + ke 2 = Ke, moo ke 1 = Ke 2 ebe ke 1 = Ke 2 = 1/2 Ke = 1/2 (0.149) = 0.0745 A.
