Problem 30.9: Find internal resistance of battery in a network

Please wait for the animation to completely load.

The batteries shown are not ideal (that is, they have internal resistances) but are otherwise identical. Assume ideal meters (current is given in milliamperes and voltage is given in volts). Vary the battery voltages and find the internal resistances. The internal resistance is the same for both. Restart.
