The capacitor has a moving and a stationary plate, both 260mm in diameter. The stationary plate is separated from the frame by an insulator, preserving its electric charge. The moving plate is connected to the base, and moves using a micrometer screw. You can adjust the spacing from 0 to 70mm, reading the distance precisely to 0.1mm.
Once the capacitor is charged, turn off the generator and nudge the string suspending the metal ball such that the ball touches the insulated plate. Once the ball touches the insulated plate, it will begin bouncing between the plates, creating a “bell” effect.
The field lines are perpendicular to the surfaces of the spheres and are stronger near the regions of higher charge density. Capacitance: The capacitance of a spherical capacitor depends on factors such as the radius of the spheres and the separation between them.
The electric field between the two spheres is uniform and radial, pointing away from the center if the outer sphere is positively charged, or towards the center if the outer sphere is negatively charged. A spherical capacitor is a space station with two layers: an inner habitat where astronauts live and an outer shell protecting them from space.
ce start piling up on one of the capacitor plates. Initially, the voltage across th plates is 0V until the charges start accumulating. Since the capacitor plates are so close to each other the electrons hitting one plate push electrons off of the othe
Therefore, the potential difference across the spherical capacitor is (353 V). Problem 4:A spherical capacitor with inner radius ( r1 = 0.05 m ) and outer radius ( r2 = 0.1 m) is charged to a potential difference of ( V = 200 V) with the inner sphere earthed. Calculate the energy stored in the capacitor.

Two metal balls in a capacitor
The situation is: let''s have a capacitor connected to a voltage souce (I guess it''s safe to assume that the capacitor is very long, so we don''t have to consider effects at its edges).

how to charge a steel ball
If you had another conductive object, you could make a two-plate capacitor in which case the required voltage could be much lower, so in theory you could charge a two plate capacitor using a much lower voltage, then move the other plate away and this would leave your original sphere charged, but this charge would soon leak away.
