Hey I am confused as to the answer to this question; not sure exactly how to figure out what the answer is because it is not a constant resistance. Any help appreciated:
The potential difference across the terminals of a battery is V_1 when there is a current of I_1 in the battery from the negative to the positive terminal. When the current is I_2 in the reverse direction, the potential difference becomes V_2. What is the internal resistance of the battery?
I tried adding and subtracting the two resistances (R_1 = V_1/I_1 and R_2 = V_2/I_2), but that isn't correct, and I'm not sure of what to do. Thanks
