Problem
A parallel-plate capacitor has a capacitance of 3.0μF when empty. While it remains connected to a 9.0V battery, a dielectric with constant κ=4.0 is fully inserted between the plates. Calculate the magnitude of the energy transferred between the battery and the capacitor during the insertion and indicate whether energy is supplied by or absorbed by the battery.
