- 3.9 m, Shells B and C. and shells D and E are connected by conducting wires as shown. You are asked to evaluate the capacitance of this system hetween shells A and F (that is, when shells A and F would be connected to the outside circuitry) What is capacitance C of this system when the space between all the shells is just air (like vacuum for our purpose)?: C= pF. the figure) is filled with an insulating material...
please answer both questions in details
Q3. For the circuit below, find: a) The voltage V, in phasor form. b) The voltage v.(t) in time domain. 3221H + 10 cos( -45°) V TF + 5 sin(t + 30°) V 1 Q4. A capacitor consists of two concentric spherical conducting shells of radii a and b as shown in the figure. The space between them is filled with a radially inhomogeneous dielectric of permittivity e(r). The capacitance of this structure is...
The figure below shows a cross-section of a long (infinite for our purposes) solenoidal system consisting of two coaxial solenoids, of radii a=4.3 cm and b=28.1 cm. These solenoids have the same number n=20 cm-1 of the turns of the wire per unit length. The wire is common and fed by the time t-dependent current I(t)=Io.sin(21f.t) but in the opposite directions as illustrated in the figure. Here the current amplitude lo=20.5 A and frequency f=148 Hz. In this problem, we...
2. The electromechanical system shown in the figure below represents a simplified model of a capacitor microphone. The system consists of a parallel plate capacitor connected into an electric circuit. Capacitor plate a is rigidly fixed to the microphone frame. Sound waves passing through the mouthpiece exert a force fs(t) on plate b, which has mass M and is connected to the frame by a set of springs and dampers The capacitance C is a function of the distance x...
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...
