What is a capacitance formula for a spherical capacitor?

The capacitance formula links physical attributes of the capacitor to its ability to hold an electric charge. For a spherical capacitor, the formula is given by: where C is the capacitance, R 1 is the radius of the inner sphere, R 2 the radius of the outer sphere, and ε 0 represents the permittivity of free space - a fundamental constant.

How do you find the charge Q on a spherical capacitor?

To find the charge Q on the spheres, we need to use the capacitance formula for a spherical capacitor: C = ₀ ₁ ₂ 4 π ε ₀ 1 R ₁ − 1 R ₂ where C is the capacitance, R₁ = 12.5 cm and R₂ = 14.8 cm are the radii of the inner and outer spheres, respectively, and ε₀ is the permittivity of free space.
