Ok! and Yess I understood the steps. Thank Youu!

Thank Youu!

OHH I got: r = 11.2 Ω and Emf = 151.2 V Would that be right? : )

Internal resistance is the resistor inside a battery and next to the emf, which is like the source, and together they give out the terminal voltage right? and I don't understand what KVL means. I drew the circuit and if I treat the circuit as an ideal cell with two resistors in series would...

No, I am not missing anything. I wrote it directly from a question in a quiz that I got wrong. In reference to the bolded part, I have no clue.

Homework Statement When an external resistor of resistance R 1 = 14 Ω is connected to the terminals of a battery, a current of 6.0 A flows through the resistor. When an external resistor of resistance R2 = 64.4 Ω is connected instead, the current is 2.0 A. Calculate the emf and the internal...
