hen a battery is connected to a 100-Ω resistor, the current is 4.00 A. When the same battery is connected to a 449-Ω resistor, the current is 1.09 A. Find the emf supplied by the battery and the internal resistance of the battery.
I know that emf is equal to current times resistance but i must be missing something here because i always come up with the wrong answer.
