Why value of hall coefficient is negative?
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
What is the fundamental carrier of electric charge?
The fundamental carrier of electric charge is the electron. The charge on one electron is 1.6021765 × 10−19 Coulomb, and is negative. Charge can't exist in any smaller quantity, and all charges are multiples of this quantity. Protons have a positive charge of the same quantity, but they stay in their respective nuclei and don't participate in the movement of charge from place to place.
What is the electric charge of a muon?
The electric charge of a muon is -1 elementary charge, which is the same as the charge of an electron.
What acts like carriers of electricity?
a charge carrier is a particle free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors.
Why the electric field and force is same for unit charge?
The numbers will be the same, because electric field is defined as "force per unit charge". The units, however, will not be the same.
Is the direction of the electric force on a charge is tangent to the field line?
No, the direction of the electric force on a charge is along the electric field vector and not necessarily tangent to the field line. The force on a charge will be in the same direction as the electric field if the charge is positive, and opposite if the charge is negative.
When two objects have the same electric charge they?
When two objects have the same electric charge, they repel each other. This is because like charges repel according to the law of electrostatics.
Are electrons the same as electric charge?
No. An electric charge is a property of certain particles (and larger amounts of matter); electrons have an electric charge of (-1) elementary units, but other particles also have electric charge. For example, protons have an electric charge of (-1), quarks may have charges like (2/3) and (-1/3), etc.
What have an electric charge?
it is neutral as the protons and the neutrons are the same amount.
When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
What is static charges?
A buildup of electric charge in an object caused by the presence of many particles with the same charge.
What is the predominant carrier of electrical charge in a copper wire?
The predominant carrier of electrical charge in a copper wire is the free electrons within the copper atoms. These free electrons are able to move easily through the lattice structure of the copper, allowing for the flow of electric current.
