Two resistors when connected in parallel give an equivalent resistance of 2 ohm and when connected in series they give an equivalen resistance of 9 ohm find the resistance of both the resistors?

(R1 * R2) / (R1 + R2) = 2 Parallel R1 + R2 = 9 Series Treating the two as simultaneous equations, and substituting for R1: ((9-R2) * R2) / (9 - R2 + R2) = 2 R2^2 - 9R2 + 18 = 0 Solving the quadratic, we get: R2 = 6 ohm R1 = 3 ohm Which you can check by substituting back into the original equations.
