Question

Two resistances R₁ and R₂ provides series to parallel equivalents as (n/1), the correct relationship between R₁ , R₂ and is

(1) \((\frac{R_1}{R_2})^2+(\frac{R_2}{R_1})^2 = n^2\)

(2) \((\frac{R_1}{R_2})^{3/2}+(\frac{R_2}{R_1})^{3/2} = n^{3/2}\)

(3) \(\frac{R_1}{R_2}+\frac{R_2}{R_1}=n\)

(4) \((\frac{R_1}{R_2})^{1/2}+(\frac{R_2}{R_1})^{1/2} = \sqrt{n}\)

Answer 1

 (4) \((\frac{R_1}{R_2})^{1/2}+(\frac{R_2}{R_1})^{1/2} = \sqrt{n}\)
