A constant potential difference of 12V is maintained between the terminals of a 0.25 micro-F parallel plate air capacitor.
A. A sheet of Mylar is inserted between the plates of the capacitor completely filling the space between the plates. When this is done how much additional charge flows into the positive plate of the capacitor? (K for mylar = 3.1)
B. What is the total induced charge on either face of the mylar sheet?
C. What effect does the mylar sheet have on the electric field between the plates? Explain how you can reconcile thiswith the increase of charge on the plates, which acts to increase the electric field.

a)
b)
c) The addition of themylar does not affect the electric field since the induced charge cancels the additional charge drawn to the plates.
