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

INSTRUCTIONS: Show your complete solution to each problem on a short bond paper. Answers must be expressed in engineering notation (when the exponent of the base 10 multiplier is not a multiple of 3, press ENG or SHIFT+ENG, whichever the case.) Example: 0.06N or 6.0x10-2 N must be expressed to 60x10-3 N or 60mN 1. A capacitor is composed of 2 plates separated by a sheet of insulating material 2mm thick and of relative permittivity 3. The distance between the plates is increased to allow the insertion of a second sheet of 3mm thick and of relative permittivity ɛr . If the equivalent capacitance is one-half of the original capacitance, find the value of ɛr. 2. In the given network, each capacitor has C = 4. 00 µF and Vab = +28.0 V. Calculate the: a. Total capacitance b. Charge on each capacitor c. Potential difference on each capacitor C4 3. A 20 µF capacitor is charged to 120 V and then disconnected from the power supply. If a second uncharged capacitor with capacitance of 50 µF is…
