## Question

If two resistors with resistances R_1 and R_2 are connected in parallel, as in the figure below, then the total resistance R, measured in ohms (Omega), is given by 1/R=1/R_1+1/R_2

If R_1 and R_2 are increasing at rates of 0.3 Omega \/s and 0.2 Omega \/s, respectively, how fast is R changing when R_1 = Omega and R_2 = Omega? (Round your answer to three decimal places.)

Omega \/s
