ANSWER: = Exercise 24.12 Description: A spherical capacitor is formed from two concentric, spherical, conducting shells separated by vacuum. The inner sphere has radius 15.0 cm and the capacitance is 116 pF. (a) What is the radius of the outer sphere? (b) If the potential difference. .. A spherical capacitor is formed from two concentric, spherical, conducting shells separated by vacuum. The inner sphere has radius 15.0 and the capacitance is 116 . Part A What is the radius of the outer sphere? ANSWER: = Part B If the potential difference between the two spheres is 220 V, what is the magnitude of charge on each sphere? ANSWER: = Exercise 24.30 Description: A parallel-plate vacuum capacitor has U of energy stored in it. The separation between the plates is x_1. If the separation is decreased to x_2, (a) what is the energy now stored if the capacitor was disconnected from the potential source before the. .. A parallel-plate vacuum capacitor has 6.58
