Vadinasi,
IₓRₓ = I₂R,
I₁R₁ = I₂R₂.
Pirmą šių lygybių padaliję panariui iš antrosios, gauname:
IₓRₓ / I₁R₁ = I₂R / I₂R₂
Iš čia išreiškiame ieškomą varžą Rₓ:
Rₓ = (R * R₁) / R₂
Kai elektrinė grandinė subalansuota, varžų santykį galime pakeisti reochordo vielos dalių ilgių santykiu (1.4.4 pav., b):
Rₓ = (R * l₁) / l₂
Bandymo su Vitstono tilteliu analizė parodė, kad, taikant vienodo potencialo taškų nustatymo metodiką, nesunku spręsti įvairius mišriojo laidininkų jungimo uždavinius.
## Klausimai ir užduotys
1. Nubraižykite elektrinę schemą, kurioje šeši vienodi 10 Ω varžos varžai būtų sujungti taip, kad pilnutinė grandinės varža būtų lygi 10 Ω.
2. 1.4.5 paveiksle, a, pavaizduotas mišrusis penkių varžų jungimas. R₁ = R₂ = R₃ = R₄ = R₅ = R.
a) Persibraižykite šią elektrinę schemą savo sąsiuvinyje ir pažymėkite joje elektros srovės kryptį.
b) Paaiškinkite, kodėl penktuoju varžu elektros srovė neteka.
c) Ar galima 1.4.5 paveiksle, a, pavaizduotą schemą pakeisti ekvivalentinėmis schemomis (1.4.5 pav., b ir c)? Atsakymą pagrįskite.
d) Apskaičiuokite pilnutinę grandinės varžą.
e) Ar galima pirminėje elektrinės grandinės schemoje (1.4.5 pav., a) įžvelgti Vitstono tiltelį? Atsakymą pagrįskite.' (Size = 4000)], CommandType='Text', CommandTimeout='30']
