Why can a wire conduct a electric current when it is connected to an electrical source?
When a wire is connected to an electrical source, it allows the flow of electrons due to the presence of free electrons within the material of the wire. The electric field created by the electrical source causes these free electrons to move, creating an electric current that can power devices or create electrical effects.

What is electical conductivity?
Electrical conductivity is a measure of a material's ability to conduct an electric current. It is determined by the availability of free electrons in the material that can move in response to an applied electric field. Materials with high electrical conductivity, like metals, allow electric current to flow easily, while insulators have low conductivity and impede the flow of current.
What is the instrument used for electrical current?
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
What is the current and how is it measured in electrical circuits?
The current in electrical circuits is the flow of electric charge. It is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the current passing through it.
What does not carry an electrical current?
Materials that do not conduct electricity are called insulators. Examples include rubber, plastic, glass, and wood, which have tightly bound electrons that do not move freely to carry an electric current.
What is the purpose of the black cable in this electrical circuit?
The purpose of the black cable in this electrical circuit is to carry the electric current from the power source to the connected devices or components in the circuit.
What is the ability to conduct electric current?
you may find the answer from the periodic tables electron orbiting the nucleus is the answer
Why do solution containing acids conduct an electric current?
To conduct an electrical current, you need movable charges. In such solutions, those are available in the form of ions.
What is A substance that conducts an electric current in solution?
A substance that dissolves in solution to conduct an electrical current is an "electrolyte" or, less commonly, an "ionogen".
Are most metals electrical insulators?
No, most metals are electrical conductors. This means that most metals will conduct an electric current in the presence of an electric field.
What is electical conductivity?

It is determined by the availability of free electrons in the material that can move in response to an applied electric field.

Can electric current pass through alcohol Explain?
Yes, alcohol is a liquid and has delocalised electrons which can carry the electrical current. Edited: Seriously? Unless there are impurities in the alcohol that are electrolytes, alcohol will NOT conduct an electric current. Alcohols are considered as NON ELECTROLYTES, as they do not ionize and thus will not conduct a current. (Dr.J.)
What is the transition element known for its excellent ability to conduct an electric current?
Copper is the transition element known for its excellent ability to conduct an electric current. It is widely used in electrical wiring due to its high conductivity and low resistance.
What is a single route for electrical current called?
A single route for electrical current is called a branch circuit.
What is the instrument used for electrical current?
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
Will a metal conduct electricity if it is kept away from any and all forms of radiation?
Yes. The ability to conduct electric current isn't connected with any radiation in the neighborhood.
What is conduct electricity means?
The ability of a material to conduct an electric current is termed as ELECTRICAL CONDUCTIVITY. Generally, ELECTRICAL CONDUCTIVITY is the ratio between ELECTRICAL FIELD STRENGTH and the CURRENT DENSITY of the conductor. The unit is Sm-1. It is also known as SPECIFIC CONDUCTANCE. ELECTRICAL CONDUCIVITY = (ELECTRICAL RESISTIVITY)-1 The unit of ELECTRICAL CONDUCIVITY is ohm- meter.
What is the current and how is it measured in electrical circuits?
The current in electrical circuits is the flow of electric charge. It is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the current passing through it.
