Where R, R1 and R2 are measured in ohms. R1 and R2 are increasing ate rates of 1.0 and 1.3 ohms per sec, respectively.

The combined electrical resistance R of two resistors R, and R2, connected In parallel, is given by the equation below, when + R2 At what rate Is R changing when R, = 57 ohms and R2 = 80 ohms? (Round your answer to three decimal places.) ohm/sec Need Help? Read It Watch It
