A battery is connected to a resistor so that current flows in the circuit. Keeping the same battery, we replace the resistor with one which has a higher resistance. Consider the following quantities: current through the battery, potential difference across the resistor (Vp). Which quantity changes (and how) and which stays the same?
A) Ibat decreases, VR increases
B) Ia decreases, V stays the same
C) Ib stays the same, VR decreases
D) I stays the same, Vn increases
