Question:

A capacitor of capacitance C with a vacuum between the plates is connected to a source of potential difference ΔV. Assume ΔV>0.

A) The capacitor is then disconnected from the potential difference source and you fill it with a dielectric that has a dielectric constant κ. What is the new charge on the plates?

Express your answer in terms of some or all of the variables C, κ, and ΔV.

B) What is the new energy stored by the capacitor?

Express your answer in terms of some or all of the variables C, κ, and ΔV.
