3. The 2.00 cm3 volume between the plates of a 225 pF parallel-plate capacitor is filled with a dielectric. The area of each plate is 0.0 400 m2 andthe platesareS00 apart. Find the permittivity of the EQUATION USED (ONE EQUAL SIGN) SOLUTION ANSWER A0.00400m To onc esigmrrican2 isurec knd the maximum cnergy density of an electric red t QUATION USED (ONE EQUAL SIGN) lene (Table 24.2, page 802) SOLUTION ANSWER 5. In vacuum, the potential difference between the non-parallel plates of a capacitor is given by Calculate the numerical value of the capacitance of this capacitor after benzene at 20'C completely fills the volume between the plates so there is no change in symmetry from the vacuum case.(Use Table 24.1, page 7SER 0.0543 m-10 (0 34 DEFINING EQUATION USED SOLUTION Step 1: With the dielectric in place, we simply replace a0 in the vacuum expression for the potential difference with60 Step 2: Substituting benzene's K from Table 24.1 then gives potential difference of (your Step 2 denominator must contain the numerical values of K and gb (0.0543 m-o of(8.854 io o F/m) Step 3: Now show all of your numbers and the necessary algebraic cancellation as you substitute your Step 2 expression into your defining equation, giving the capacitance =

Explanation / Answer

Q3.

C = E*A / d

Where d = distance between plates
A = Area of plates
E = permittivity
C = Capacitance

So,
225*10^-12 = (E*0.00400) / (500*10^-6)
=> E = 2.8*10^-11 F/m
