Question

Calculate the equivalent resistance between points

Answer 1

1.Equivalent Resistance between BE, (1Ω, 2Ω, 3Ω are in series) is R₁

R₁ = 1 + 2 + 3 = 6Ω 

R₁ is in parallel to R₂ = 3Ω their resultant R.3 1/r₃ = 1/r₁ +1/r₂ = 1/6 + 1/3 = 1+2/6 = 1/6 Between BE 

∴ R₃ = 2Ω 

(ii) Equivalent resistance between A and F i.e. R₄ , R₂ , Rs are in series 

3Ω, 2Ω and 3Ω are in series 

R= 3 + 2 + 3 = 8₁₂
