The capacitance between two concentric spheres is determined by the radius of the spheres and the permittivity of the material between them. It can be calculated using the formula C 4rr / (r - r), where C is the capacitance, is the permittivity of free space, r is the radius of the inner sphere, and r is the radius of the outer sphere.

What is the difference between self capacitance and mutual capacitance in the context of capacitive touch technology?
Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.
What is the potential between two charged spheres?
The potential between two charged spheres is the amount of electrical energy per unit charge that can be stored or transferred between them. It is determined by the distance between the spheres and the amount of charge they possess.
What is the distance between two spheres each with a charge?
The distance between two charged spheres affects the strength of the electrostatic force between them, given by Coulomb's law. The force decreases as the distance between the spheres increases. The distance influences the magnitude of the force between the spheres.
What force would pull two spheres together?
They are being pulled by the force of gravity
How two metal spheres can be charged by induction?
To charge two metal spheres by induction, bring a charged object near the first sphere, inducing opposite charges in the spheres by polarization. Ground one of the spheres momentarily to allow excess charges to flow and redistribute between the spheres, resulting in both spheres being charged.
Is it true that If two spheres have the same center but different radii they are called concentric spheres.?
True
What is the mutual capacitance of two spheres?
The capacitance of two spheres can be calculated using the 'method of images' repeatedly. This gives the result as a fast converging series. Details: http://www.iue.tuwien.ac.at/phd/wasshuber/node77.html
Why do concentric cables hold a capacitive charge?
any two conductive surfaces will have capacitance between them, when one conductor surounds the other, the effect become large enough to be significant
Does capacitance exists between two current carrying conductors?
Capacitance exists between any two conductors, current carrying or not.
What is the difference between self capacitance and mutual capacitance in the context of capacitive touch technology?
Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.
What is the potential between two charged spheres?
The potential between two charged spheres is the amount of electrical energy per unit charge that can be stored or transferred between them. It is determined by the distance between the spheres and the amount of charge they possess.
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
What is the space between two concentric circles called?
Annulus
What is the distance between two spheres each with a charge?
The distance between two charged spheres affects the strength of the electrostatic force between them, given by Coulomb's law. The force decreases as the distance between the spheres increases. The distance influences the magnitude of the force between the spheres.
Why transition capacitance called so?
Transition capacitance is the capacitance that is accumulated between two terminals as an electrical charge is carried between them. In a diode, this is the diffusion from anode to cathode of a diode in forward bias mode.
What does the gravitational force between two massive spheres do?
The gravitational force between two massive spheres attracts them towards each other. This force is proportional to the product of the masses of the spheres and inversely proportional to the square of the distance between them.
What is term for the potential different in a charge between two points in a current path?
capacitance
