For this section: it parallel plate air capacitor has a capacitance of 5.0 F. What is its capacitance if the separation between the plates is decreased 2 points to one-half its original value while keeping all the other factors constant? What is its capacitance if the area of the plates is decreased to one- half 2 points its original value while keeping all the other factors constant? What is the capacitance if the dielectric of relative permeability of 2 is 2 points inserted between the plates of the original air capacitor
