10 resistors of` 2 Omega` each are connected in parellel. Calculate the effective resistance.

An effective resistance R is obtained by connecting 'n' identical resistors each resistance 'r' in series.When connected in parallel,the effective resistance of the combination is

A set of 'n' identical resistors each of resistance R ohm. When connected in series have an effective resistance of X ohm and when the resistors are connected in parallel, the effective resistance is Y ohm. Find the relation between R, X and Y.

Three resistors 2Omega , 4Omega and 5Omega are combined in parallel. What is the total resistance of the combination?

Three resistances of 2Omega each are connected in a triangle.The resistance between two vertices is

Rp is the equivalent resistance of n equal resistors connected in parallel and Rs the equivalent resistance when they are connected in series. Then ""^(Rs//_(Rp) is
