A dielectric is inserted into a capacitor while the charge on it is kept constant. What happens to the potential difference and the stored energy? 

Below, three different arrangement of identical capacitors are shown. What is the correct order of total capacitance values for the arrangements, greatest first?

A negative charge is located in the uniform electric field between two plates (not shown).
Where in the diagram will the electron have the greatest change in potential energy before hitting the one of the plates?

A $$5F$$ capacitor holds $$100C$$ of charge when it is connected to a power supply. The $$5F$$ capacitor is removed and replaced with two $$40F$$ capacitors in series with each other, the power supply remains untouched.
What is the new charge stored in one of the two $$40F$$ capacitors?

Each capacitor in the circuit shown is a $$1F$$ capacitor.
What potential across $$A$$ and $$B$$ would result in $$2$$ Coulombs of charge on each plate of each capacitor?

Each capacitor in the circuit shown is a $$1F$$ capacitor. What would be the equivalent capacitance between $$A$$ and $$B$$?

A student is working on a circuitry project and wants to create an equivalent capacitance of $$700F$$. However, the student's only supply is a bag of $$470F$$ capacitors.
How can the student arrange any number of the $$470F$$ capacitors so that their equivalent capacitance is as close to $$700F$$ as possible?

An air-filled capacitor has a capacitance of $$C^o$$. Then a dielectric with a dielectric constant of 3.0 is inserted into it and the plates are pushed toward each other so that the distance between the plates is reduced to $$\frac{1}{2}$$ the original value.
What is the new capacitance?

A capacitor contains two square plates with side lengths $$5.0$$ cm. The plates are separated by $$2.0$$ mm. Dry air fills the space between the plates. Dry air has a dielectric constant of $$1.00$$ and experiences dielectric breakdown when the electric field exceeds $$3.010^4 V/cm$$.
What is the magnitude of charge that can be stored on each plate before the capacitor exceeds its breakdown limit and sends a spark between the plates?

Three identical capacitors, each of capacitance $$C$$, are wired as shown above
When both switches are closed, the equivalent capacitance is:
