The simple oscillating circuit shown above is made from a parallel plate capacitor connected to a solenoid. The capacitor has plates 3.0 cm x 6.0 cm separated by 2.0 mm and filled with a material with a dielectric constant x- 8.0. The air-filled solenoid is 12.0 cm in length, with a diameter of 2.5 cm, and wound with 150 turns. The capacitor is charged to 0.25 uC, and the switch is closed at time t-0. A) What frequency radio wave...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
