Question 4: What are the charge on and the potential difference across each capacitor in the figure to the right? (Note: You may want to find the equivalent capacitance of a single capacitor that could replace the three capacitors, find the charge it will take from the battery, then work backward to the situation with the three capacitors.)

Analyze the spherical capacitor below and convince yourself that it is two capacitors that are in parallel to each other (common top and bottom plate). The relative permittivities in the two regions are 2 and 3. If the inner radius is 2mm and outer radius is 4mm, determine the total capacitance of the spherical capacitor. Hint: This is similar to parallel plate capacitor, except that you will use the formula for spherical capacitors. b Er2 Eri O 1.3352 pF 481.5644 pF 2.2253 pF 802.6074 pF

A parallel-plate capacitor is constructed by filling the space between two square plates with a block of three dielectric materials, as shown in the figure below. You may assume that ℓ ≫ d. A parallel-plate capacitor is comprised of two square plates with sides of length ℓ and separation distance d. There are three dielectric materials in the space between the capacitor plates. A material with length ℓ⁄2, height d, and dielectric constant ?1 fills the left half of the space. A material with length ℓ⁄2, height d⁄2, and dielectric constant ?2 fills the top right quarter of the space. A material with length ℓ⁄2, height d⁄2, and dielectric constant ?3 fills the bottom right quarter of the space. (a) Find an expression for the capacitance of the device in terms of the plate area A and d, ?1, ?2, and ?3. (Use the following as necessary: ?1, ?2, ?3, ?0, A and d.)C = (b) Calculate the capacitance using the values A = 1.30 cm2, d = 2.00 mm, ?1 = 4.90, ?2 = 5.60, and ?3 = 2.50.
The capacitors in Sample Problem No. 4 are connected in parallel instead of being in series. The combination is connected to a 100 V line. Find the (a) total capacitance, (b) charge stored in each capacitor, and (c) difference across each capacitor. Sample No. 4: 4. Two capacitors with 2.0 F and 3.0 F capacitance, respectively, are connected in series and subjected to a total potential difference of 100 V.
