Explanation

When three identical resistors are connected in series, the total resistance is three times the resistance of one resistor (R_series = 3R). When connected in parallel, the equivalent resistance is one-third of a single resistor (R_parallel = R/3). Therefore, the ratio of the parallel resistance to the series resistance is (R/3) / (3R) = 1/9, meaning the series resistance is 9 times greater than the parallel resistance.
