The spark is caused by the buildup of excess charge on your finger as it gets closer to the positively charged van de Graaff generator. At a certain point, the electric field between your finger and the generator becomes strong enough to ionize the air molecules, creating a conductive path for the excess charge to flow through in the form of a spark.

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 are spherical wave fronts are viewed as?
Spherical wave fronts are viewed as concentric spheres originating from a point source of radiation in all directions. They represent the expanding wave fronts of electromagnetic waves or sound waves propagating outwards from the source.
What is the capacitance between two concentric spheres?
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 conducting and non conducting sphere?
Conducting spheres allow for the flow of electric charge, while non-conducting spheres do not. Conducting spheres can redistribute charge in response to an external electric field, while non-conducting spheres cannot. Conducting spheres are typically made of metals, while non-conducting spheres are typically made of insulating materials.
How are elliptical galaxies perfect spheres?
They are not perfect spheres. If they were, they would have been called spherical, not elliptical!
Are the moon sun and the earth perfect spheres?
No but they are of a spherical shape
What shape are planet?
The inner planets have a spherical shape. In fact all planets are more or less spherical.
Are the sun and planets round?
Yes!!!! The correct term is "spherical", which means round in all dimensions like a ball. (A hoop is round, but is not spherical) Stars and planets are not perfect spheres, but they are very close to perfect spheres.
What shape is the earth and moon?
Spherical. They are approximately spheres. The earth is more of an oblate sphere, a squashed sphere - this is due to its spin.
How do planets develop their spherical shape?
Gravity pulls the asteroids into spheres when they get big enough.
When an aircraft travels quicker than the spherical waves it produces the overlapping spheres form?
A shock wave
Why is Mercury spherical?
The reason Mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.
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 do the orange and yellow spheres represent in a model of an atomic nucleus?
The orange spheres represent protons, which have a positive charge, and the yellow spheres represent neutrons, which have no charge. Protons and neutrons make up the majority of the mass of an atomic nucleus.
Why do slightly non spherical particles aspect ratio 1.03 pack denser than perfectly spherical particles?
A sphere cannot "tile" with other spheres as well as, for example, a cube can with other cubes. This results in more empty space between the particles, and therefore a lower density. Also, there's no such thing as a "perfect" sphere, or circle.
What is the study of spheres and cylinders in math called?
Spheres and cylinders are studied in geometry. In fact there is a geometry that just deals with spheres called spherical geometry. Imagine living on a sphere ( you almost do) compared to living on a plane. Some geometric postulates must be modified for this.There is a geometry of living on the surface of a cylinder too.
