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.
