Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
What is a current carrier Valence electron Proton Free electron or Ion?
A current carrier can be any of the following: valence electron in a conductor, free electron in a semiconductor or metal, ion in an electrolyte, or proton in a hydrogen ion conductor. Ultimately, it depends on the material and conditions under which the current is being carried.
Is the electric current in a metal conductor is carried by positive ions?
Yes
The electric current in a metal conductor is carried by?
The electric current in a metal conductor is carried by the flow of electrons. Electrons are negatively charged particles that move in response to an electric field, allowing for the transfer of energy and the generation of electrical power.
What particles carry electric current through metal wires?
In metal wires, electric current is carried by electrons. Electrons are the negatively charged particles that flow through the conductor when a voltage is applied, creating the flow of electricity.
Why is a metal with three outer electrons a better conductor that a metal with one outer electron?
Because an electric current is basically electrons moving along, so if there are more slightly freer electrons there wil be a greater facility for electron movement.
Is metal coat hanger a conductor or insulator?
A metal coat hanger is a conductor of electricity because it is made of metal, which allows electric current to flow through it easily. Insulators, on the other hand, do not allow electric current to flow through them easily.
What happens to metals as they conduct electricity?
The electrons in a conductor will support the movement of electric current. A conductor is defined as a material with a number of electrons in its makeup that are actually in what is called the conduction band. The conduction band is an energy level where electrons must be to permit conduction in a material. If the minimum energy in the conduction band in a material is such that a lot of electrons in that material are already at or above that level, then these electrons will be available to support current flow. Remember that electron current flow is moving electrons, and it is not about sending an electron into a conductor, like a wire, at one end and getting that same electron out at the other. It is about sending a bunch of them in at one end, and all the electrons already in the conductor move over and a bunch come out the other end. The electrons already in the conduction band within the conductor support current flow in this way.
Is a dime an insulator or conductor?
A dime is a conductor of electricity because it is made of metal. Metal objects like dimes allow electric current to flow through them easily.
How does large amount of current flow through a conductor despite low drift velocity and small charge on an electron?
This is because the number of electrons (or charge carriers) in a conductor is very very high; such as, up to 1023 electrons in unit area of a metal conductor. The combined effect of the drift velocities and charges in the entire body of the conductor enable the flow of huge amount of charges (current) through it.
Why is liquid mercury a good electrical conductor?
Liquid mercury is a good electrical conductor due to its high electron mobility and low resistivity. The electrons in the liquid metal are able to move freely, allowing for the easy flow of electric current. Additionally, mercury has a high density, which helps to facilitate electron conduction.
What metal is a good conductor of thermal energy and electric current?
aluminum, copper,
