Two equal parallel plate capacitors, each with area "A" and plate separation "d", areconnected in parallel with a voltage "V" applied between them. after the capacitors are fully charged the voltage source is removed. Given [A,d,V,K].
If a dielectirc with a value K is inserted into one of the capacitors, determine;
a. The free and bound charges on each plate.
b. The voltage across the capacitors.
c. The electric field between the plates of both capacitors.
