Main Objectives:
- Be able to define capacitance and determine the capacitance of arrangements of
conductors in simple cases.
- Be able to explain why inserting a dielectric in a capacitor increases its capacitance.
- Be able to calculate the equivalent capacitance for arrangements of several capacitors
connected in series and parallel.
- Be able to calculate the amount of energy stored in a capacitor.
- Be able to simplify electric circuits using combinations of resistors in series and
parallel
