What is the relationship between charge density and current density in a given material?
The relationship between charge density and current density in a material is that current density is directly proportional to charge density. This means that as the charge density increases, the current density also increases. Charge density refers to the amount of charge per unit volume in a material, while current density is the flow of charge per unit area. Therefore, a higher charge density will result in a higher current density in the material.
What is the relationship between surface charge density and volume charge density in a given system?
Surface charge density and volume charge density are related in a given system by the equation: surface charge density volume charge density thickness of the system. This means that the amount of charge distributed on the surface of an object is directly proportional to the volume charge density within the object and the thickness of the object.
What is the charge density formula for a sphere?
The charge density formula for a sphere is Q / V, where is the charge density, Q is the total charge, and V is the volume of the sphere.
What makes a negative charge negative?
As I understand , there cannot be any standing alone, independent, souvereign negative or positive charge. If as a result of some work something get negatively charged or if a negative charge appeared somewhere, this means something get positively charged or a positive charge appeared somewhere too. Charge means potential energy and if this energy is then released during discharge a next work is produced, charges are neutralized, but the work has produced some other energy with its further possible (potential) work, and so on in the universe.
What electrons have a charge?
Electron's have a negative charge, Protons have a positive charge.
What electric charge can either be positive or negative?
Positive charge is one of the two possible electrical charges, the other is ..........? the NEGATIVE charge.
What is the physical meaning of charge density on lines or on areas?
Every object consists of a certain amount of positive charge and a certain amount of negative charge. For neutral objects, the amount of each type of charge is equal in every tiny, or infinitesimal, portion of the object. If the object has the shape of a line, the amount of positive charge in each tiny segment of length along the line is equal to the amount of negative charge in each tiny segment of length. For a neutral three-dimensional object, such as a cube, the amount of negative charge in each small volume element of the total volume of the cube is equal to the amount of positive charge in each small volume element. All neutral objects have a charge density of zero throughout their volumes despite the fact that they have charge. The charge density describes the amount of excess charge per given region of space. For objects that are not neutral, then, the charge density is either positive or negative. A positive charge density expresses the fact that an object has a given amount of positive charge more than it has negative charge in a specific region of space. Likewise, a negative charge density means the object has a given amount of negative charge more than positive charge for a given region of space. For a line of charge, the charge density is expressed as Coulombs per meter when using SI units. For a two-dimensional object, such as a disk, the charge density using SI units is Coulombs per (meter^2). For objects that have uniform excess charge throughout their volume, the charge density is expressed as the total amount of excess charge on the body divided by the total length/ area/ volume of the body. For objects that have nonuniform charge excesses, the charge density must be expressed as a function of position (and possibly, time) within the object.
Does your hair have a negative or positive charge?
Niether. Our hair are electrically neutral as they are insulators. However by friction, it is possible to charge them either positive or negative.
Who showed the electrons carried the smallest possible negative charge?
Millikan
How do bonded atoms become partially charged?
Due to the difference in the electronegativities of the bonded atoms, the more electronegative atom attracts the shared pair of electrons towards itself, which increases the negative charge density around the attracting atom, consequently the other atom has less negative charge density and thus a positive charge density (relatively positive) gets generated at the donor atom.
Why does the oxygen atom of a water molecule have a negative charge?
The oxygen atom in a water molecule has a partial negative charge because it is more electronegative than the hydrogen atoms it is bonded to. This causes electron density to be pulled towards the oxygen atom, giving it a slight negative charge.
What is the overall charge of the atom since the atom contains positive charges and negative charges. how is that possible?
An atom is always neutral of charge, meaning ZERO. This is possible because of the equal numbers of (positive) protons and (negative) electrons, each plus charge is compensated by one (equally negative) minus charge.
What is the relationship between charge density and current density in a given material?
The relationship between charge density and current density in a material is that current density is directly proportional to charge density. This means that as the charge density increases, the current density also increases. Charge density refers to the amount of charge per unit volume in a material, while current density is the flow of charge per unit area. Therefore, a higher charge density will result in a higher current density in the material.
What charge is electrons?
Electrons charge is a negative
What charge is a negative?
A charge which is not a positive charge is a negative charge.
What is the relationship between surface charge density and volume charge density in a given system?
Surface charge density and volume charge density are related in a given system by the equation: surface charge density volume charge density thickness of the system. This means that the amount of charge distributed on the surface of an object is directly proportional to the volume charge density within the object and the thickness of the object.
Electrons characteristically have a?
The electron has a negative electrical charge.
