The potential difference across the terminals of a battery is
8.40 V when there is a current of 1.50 A in the battery
from the negative to the positive terminal. When the
current is 3.50 A in the reverse direction, the potential
difference becomes 10.20V. (a) What is the internal
resistance of the battery? (b) What is the emf of the
battery?
