Equivalent Resistance of Parallel #8211; 1/R<sub>eq</sub> = 1/R<sub>1</sub> + 1/R<sub>2</sub> + 1/R<sub>3</sub> R<sub>eq</sub> = (R<sub>1</sub><sup>-1</sup> + R<sub>2</sub><sup>-1</sup> + R<sub>3</sub><sup>-1</sup>) equivalent resistance is smaller than the minimum value of resistance in the combination.
