Please answer 1-3 A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has a radius of ra = 12.1 cm , and the outer sphere has a radius of rb = 15.1 cm . A potential difference of 120 V is applied to the capacitor. 1. What is the capacitance of the capacitor? Use ϵ0 = 8.85×10−12 F/m for the permittivity of free space. 2.What is the magnitude E1 of the electric...
Show the steps. Thank you 9. An isolated spherical spherical capacitor has charge +Q on its inner conductor (radius ra) and charge-Q on is outer conductor (radius rb). Half of the volume between the conductors is then filled with a liquid dielectric of constant K. Given [ra, Tb, Q, K] Determine: a. the capacitance of the half filled capacitor. b. The Electric Field in the volume between the two conductors as a function of distance r from the center of...

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...
