You are given n-resistors each of resistance r. These are first connected to get minimum possible resistance. In second case again connected to the maximum possible resistance. Compare the ratio between the minimum and maximum value of resistance so obtained?

n equal resistors are first connected in series and then connected in parallel. What is the ratio of the maximum to the minimum resistance?

A student has 10 resistors each of resistance r, From the given resistors, the minimum resistance made by him is

n conductors, each of resistance r, when connected in parallel, give an effetive resistance R. What will be resistance, if they are connected in series?

You are given n resistors each of resistance r .These are first connected to get minimum resistance .In the secoind case these are again connected differently to get maximum possible resistance. Compute the ratio between the minimum and maximum value of resistance so obtained.

Given three resistors of resistances 1Q (Ohm), 2Q (Ohm) and 3Q (Ohm). How will you combine them to get an equivalent resistance of 11/(5Omega) (Ohm) ?
