For n number of resistors of magnitude r connected in parallel, the equivalent resistance in R. What will be the value of the equivalent resistance when they are connected in series? Or, show that if n identical conductors are joined in series, the combined resistance is n^2 times as great as when they are joined in parallel.

You are given several identical resistances,each of value R= 10 Omega and each capable of carrying a maximum current of 1A. It is required to make a suitable combination of these resistances to obtain a resistance of 5 Omega which can carry a current of 4A, FInd the mninimum number of resistances of the type R that will be required.
