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…

A parallel plate capacitor is constructed using plates of area A and a spacing between the plates d with air in the region between. That capacitor has a capacitance of 88pF. A graduate student attempts to make a copy but mistakenly uses inches rather than centimeters for all the dimensions, so all dimensions are 2.54 times larger than the original. What is the capacitance of the graduate student's capacitor (in pF)?
