The plates have an area of 2.28 Tmn2 and are separated by a distance af 272 um, Problem 1 Problem 2 Problem 3 (A) What is the capacitance of this filled capacitor? (B) What is the capcitance of this capacitor when it is empty? (C) If the filled capacitor is connected to a 9 volt battery, what is the charge stored on the plates of this filled capacltor? D) If the dielectric is removed from this capacitor, and the capacitor rermains connected to the 9 volt battery, what is the vtage across the eripty capacitor? (E) If the dielectric is removed from this capacitor, and the capacitor remains connected to the 9 volt battery, what is the charge stored on the plates of the empty capacitor (F) After removing the dielectric, the pates are insulated so that the charge on thern remains fixed. If the batery is then disconnected, after the dielectric has been removed, what is the charge on the plates? (G) If the dielectric is then re-Inserted, with the plates insultated so that the charge remains fixed, what is the voltage across the capacitor with the dielectric re- inserted?

Explanation / Answer

a). C=k esilon_not*A/d= 2.77*8.85*10^-12* 2.26"10^-6/(2.72*10^-6)= 20.369

*10^-12 F

------

b). Co= C/k= 7.353*10^-12 F

-------

c).

Q= Cv= 20.369*10^-12* 9= 1.833*10^-10 C

------

d). V= 9V

-------

e).Qo= Co* V= 7.353*10^-12*9= 66.177*10^-12 C

-------

f). Charge remains constant

Qo= 66.177*10^-12 C

---------

g).

V= Qo/C= 66.177*10^-12/(20.369*10^-12)= 3.249 V

----------
