In circuit A, a resistor of resistance R is connected across the terminals of a battery with no internal resistance. In circuit B, an identical resistor is connected across a battery which is identical to the battery in the other circuit, except it has internal resistance r. 75.0% less power is dissipated in the resistor in circuit B than the resistor in circuit A. Determine the ratio r/R. Remember to express the answer with three significant digits.
