A 12 volt battery has an open circuit voltage of 12.65 volts and an internal resistance of 0.38 ohms. If a load with a resistance of 4.8 ohms is placed across the battery terminals determine the load current and voltage.
I load = 2 amps: Vt = 12 volts
I load = 2.44 amps: Vt = 11.72 volts
I load = 2.63 amps: Vt = 12.65 volts
I load = 5 amps: Vt = 12.72 volts
