Valence shell electrons. A metal is formed from a lattice of positive ions in a sea of delocalized electrons. These electrons are the valence shell electrons of the metal atoms and they are the ones that carry the charge during conduction.
An electric current can be produced by connecting a power source (such as a battery) to a closed circuit that includes a conductive material, like a metal wire. When the circuit is closed, the power source creates a flow of electrons through the wire, generating an electric current.
Charges that provide current in a cell are produced by the chemical reactions that occur between the electrolytes and electrodes within the cell. These reactions create a flow of electrons, which is what we refer to as electric current.
Two electrodes in electrolyte solutions
The reason why we feel electric current passing through our bodies is because it has two effects on our body tissues.1) the current stimulates nerves and muscle fibers, which produce pain and contraction of muscles.2) the tissue heats through dissipation of the electrical energy.Most people begin to feel electrical currents when it reaches a magnitude of 500uA(microAmps)
asked this same question on yahoo answers bit.ly/bI4XxE, got this response: This piece of equipment is more commonly used in a dental laboratory. It would be used in production of things such as porcelain fused to metal(PFM) crowns or metal framework in dentures. Anything that would require metal to be cast for a specific purpose.
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
Yes
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.
The valance electrons.
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.
aluminum, copper,
It is called, "electric current", and is measured in "Amperes".
Tranition metals
Yes, metals when wet conduct electricity/electric current.
A screw contact is typically made of metal, which is a conductor. This means it allows the flow of electric current through it.
the metal that serves as the best conductor of electric charge is the METAL
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.
