A 6.0 V battery is connected to two 7.70 kilo-Ohm resistors in series. An ammeter of internal resistance 0.570 Ohm measures the current and at the same time a voltmeter with internal resistance 15.2 kilo-Ohm measures the voltage across one of the 7.70 kilo-Ohm resistors in the circuit. What does the ammeter read? What does the voltmeter read?

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.
