6 FAQs about [Spherical capacitor external aria]
What is the inner sphere of a spherical capacitor?
Inner Sphere (Conductor): The inner sphere of a spherical capacitor is a metallic conductor characterized by its spherical shape, functioning as one of the capacitor’s electrodes.
What does it mean when a spherical capacitor is earthed?
When the inner sphere of a spherical capacitor is earthed, it means that the inner sphere is connected to the ground, which has a potential of zero. Any charge that was initially on the inner sphere is neutralized because the earth can supply or absorb an unlimited amount of charge.
What is the capacitance of a spherical capacitor?
Therefore, the capacitance of the spherical capacitor is (7.08 pF). Problem 2: A spherical capacitor with an inner radius (r1 = 0.1 m) and an outer radius (r2 = 0.3 m) is charged to a potential difference of (V = 100 V) Calculate the energy stored in the capacitor.
Why do sphere capacitors have high capacitance?
High Capacitance: Spherical capacitors can have relatively high capacitance values compared to parallel-plate capacitors with the same surface area. This is because the electric field is concentrated near the surfaces of the spheres, allowing for efficient charge storage.
How does the capacitance of a spherical capacitor affect radii?
The capacitance of a spherical capacitor depends on the radii of both spheres. As the distance between the spheres decreases (r<sub>2</sub> – r<sub>1</sub> becomes smaller), the capacitance increases. The presence of a dielectric material between the spheres increases the capacitance. Applications
What is the electric field of a spherical capacitor?
The electric field in a spherical capacitor is not uniform and varies with the distance from the center of the spheres. It is stronger closer to the inner sphere and weaker closer to the outer sphere. Structure: Inner Shell: A solid or hollow sphere of conducting material.
