Answer to Question #71500 in Molecular Physics | Thermodynamics for Nico Pedroza

Question #71500
Andy wants to measure the internal resistance of a 9V battery. When he connects the battery directly to a voltmeter, the meter measure 9.0V. When he connects the battery with a 10ohm resistor and use a voltmeter to measure the voltage across the resistor, the meter measure 8.5V. What is the resistance of the internal resistor? What are current going through the battery in both situations? How would you connect the ammeter in order to measure the current going through the internal resistor?
