A dielectric slab of thickness b and dielectric constant k isplaced between the plates of a parallel plate capacitor of platearea A and separation d. A potential difference ?o is applied withno dielectric present. The battery is then disconnected and thedielectric lab is inserted. Assume that ?=100cm2,?=1.0cm,?=0.50c,?=7.0 and Vo=100 ?.
a. The capacitance ?o before the slab is inserted.
b. The capacitance C with the slab inserted.
c. The free charge q.
d. The electric field, ?o in the gap.
e. The electric field, E, in the dielectric.
f. The electric displacement, D, in the dielectric.
g. Polarization, P, in the dielectric
