Please answer the given question 6
Q.6. Calculate the total effective resistance between points A and B
(i)

(ii)

(iii)

Dear student,
Resistors in series
R_S = R₁ +R₂ + R₃+....+R_n
Resistors in parallel
1/R_P = 1/R₁ + 1/R₂ +......+1/R_n

1) 1/R_P1 = (1/1 +1/1 + 1/1)​ =3
        R_P1    =  1/3
   1/R_P2   = 3
      R_P2   =  1/3
Effective resistance = 1/3 + 1 + 1/3
                                = 1+ 2/3 = 5/3 Ω 
    

2) 1/R_P = 1/6 + 1/6 = 2/6 = 1/3 Ω
      Effective resistance  =  3 Ω

3) R = (1/2 + 1/2) + ( 1/2 + 1/2 ) + 2 
         =  1 + 1 + 2 = 4 Ω
