Judge the equivalent resistance when the following are connected in parallel: 1`Omega` and `10^6 Omega`

Judge the equivalent resistance when the following are connected in parallel: 1 Omega and 10^3Omega and 10^6 Omega

Judge the equivalent resitance when the following are connected in parallel 1 ohm and 10^4 ohm

With the help of a diagram derive the formula for the equivalent resistance of three resistances connected in parallels?

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

Two resistances when connected in series give a resistance of 9Q and when connected in parallel gives a resistance of 2Omega .Calculate the.value of each resistance.
