Chapter 2, Problem P2.84(choose chapter or problem)
We can model a certain battery as a voltage source in series with a resistance. The opencircuit voltage of the battery is 9 V. When a 100- resistor is placed across the terminals of the battery, the voltage drops to 6 V. Determine the internal resistance (Thvenin resistance) of the battery.
