At the end of this lesson you should :

• Know the basic definition of capacitance and the equation for finding the potential difference between two points in an elelctric field in order to calculate the capacitance of capacitors for cases of simple geometry.
• Be able to determine the equivalent capacitance of a network of capacitors in series-parallel combinations.
• Be able to make calculations involving the relationships among potential, charge, capacitance, stored energy and energy density for capacitors.
• Be able to calculate the capacitance, potential difference and stored energy of a capacitor filled or partially filled with a dielectric.
