(a) Given n resistors each of resistance R, how will you combine them to get the (i) maximum (ii) minimum effective resistance? What is the ratio of the maximum to minimum resistance?
(b) Given the resistances of `1 Omega, 2 Omega, 3 Omega`, how will be combine them to get an equivalent resistance of (i) `(11//3) Omega` (ii) `(11//5) Omega`, (iii) `6 Omega`, (iv) `(6//11) Omega`?
(c) Determine the equivalent resistance of networks shown in Fig. 3.31.

Explanation

(i) in series (ii) all in parallel ,`n^2 `.
