The spherical surfaces r = 3 and r = 5 cm are perfectly conducting, and the total current passing radially outward through the medium between the surfaces is 3 A dc. (a) Find the voltage and resistance between the spheres, and E in the region between them, if a conducting material having sigma = 0.05 S/m is present for 3 < r < 5 cm. (b) Repeat if sigma = 0.0005/r for 3 < r < 5 cm. (c) Show that integrating the power dissipated per unit volume in part b over the volume gives the total dissipated power.

A non-conducting thick spherical shell with inner radius a = 5 cm and outer radius b = 10 cm has a uniformly distributed volume charge density of p = 1.3 nC/m2. a) What is the total charge on the shell? Hint: think of the shell as a solid sphere with a volume in the center that's missing. b) Calculate the maximum electric field strength. c) Calculate the electric field at r = 2 cm. d) Calculate a symbolic equation for...
A solid conducting sphere of radius r = 1 cm is embedded at the
boundary between a dielectric and air such that half of the sphere
is in the dielectric and half is in the air. This conguration is
shown in cross-section in the accompanying gure. The total charge
on the sphere is 1 nC.

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...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
