You have been handed an unknown battery. Using your multimeter, you determine that when a 5.00-Ω resistor is connected across the battery’s terminals, the current in the battery is 0.500 A. When this resistor is replaced by an 11-Ω resistor, the current drops to 0.250A. From those data, find (a) the emf (Voltage) and (b) internal resistance of the battery.
