Two electrical resistors (one of variable resistance x and one with fixed resistance R1) are put in parallel into a circuit. The combined resistance R, of those two resistors is given by the formula (1/R) = (1/x) + (1/R1). Solve this equation for R. Your answer will be a rational function in x and will include the constant R1. Determine the horizontal asymptote of this function when R1=2000 ohms and then answer the question: As the resistance of x approaches infinity, what is the combined resistance of the two resistors parallel?

Question
