Question

A set of n-identical resistor each resistance R ohm when connected in series habe an effective resistance of ohm and when the resistor are connected in parallel the effective resistance is Yohm.find the relation between R,XandY?

Answer 1

by 1st situation nR = X

and by 2nd we get R/n = Y

so by putting value of n in next eq. we get

R^2 = XY
