# Filling a Capacitor with Dielectric Material#

An air-filled capacitor is made from two flat parallel plates $${{params.d }} \textrm{ mm}$$ apart. The inside area of each plate is $${{params.a }} \rm\ cm^2$$.

## Part 1#

What is the capacitance of this set of plates? Enter your answer in units of pF.

Please enter a numeric value.

## Part 2#

If the region between the conductors is filled with a material whose dielectric constant is $${{params.k }}$$, what is the new capacitance? Enter your answer in units of pF.

Please enter a numeric value.
