8. Determine the equivalent capacitance of the combination shown below when C = 24 μF. Hint: Re-draw the figure to clearly see what is in parallel with what and what is in series with what 2C 2C 2C 2C 9. A parallel plate capacitor of capacitance Co has plates of area A separated by a distance d. When it is connected to a battery of voltage Vo, a charge of magnitude Q is stored on its plates. The plates are pulled apart to a separation 2d while the capacitor remains connected to the battery, what are now the magnitude of the charge on the plates and the potential difference between them? 10. a) What is the equivalent capacitance of the circuit shown below? b) What does the capacitance of the circuit changes to if a piece of Teflon (dielectric constant=2.1) is inserted between the plates in each of the capacitors?
