Two capacitors of capacitances 1.1 μF and 4.7 μF are each
charged separately by being connected across a 7.8 V battery. After
being fully charged, they are disconnected from the battery and
then connected to each other using wires so that the plates of
opposite charges are connected together. What will be the magnitude
of the final voltage (in V) across the 4.7 μF capacitor?
