∙ 13y agoElectric current moves through wires or conductive materials in a closed loop circuit, from the positive terminal of the power source to the negative terminal. Electrons carry the negative charge and flow from the negative terminal to the positive terminal.
Current is produced when charges are accelerated by an electric field to move to a position of lower electric potential.
Electric current is produced when charged particles, such as electrons, move through a conductive material, creating a flow of electric charge. The movement of these charged particles generates an electric field, leading to the flow of current in a closed circuit.
Materials that allow electric current to move through them are called conductors. Common examples include metals such as copper, silver, and aluminum. Conductors have low resistance to the flow of electric current due to their ability to easily transfer electrons.
An electric current in a metal consists of the movement of free electrons. These electrons are loosely bound to the metal atoms and can move freely throughout the material in response to an applied electric field.
A material that carries electric current easily is called a conductor, while a material that does not is called an insulator. Conductors have free electrons that can move easily in response to an electric field, allowing the flow of current. Insulators have tightly bound electrons that do not move easily, preventing the flow of current.

Ionic compounds in solution can conduct electric current because the ions are free to move and carry electric charge. When an ionic compound dissolves in water, it dissociates into its constituent ions, which are then able to move and carry the electric current.
An electric current is produced when charges are accelerated by an electric field and move to a position of potential energy difference. This movement of charges generates a flow of electric charge that constitutes an electric current.

To have electric current, you need a source of electric potential difference (voltage), a closed circuit that allows the flow of charges, and a conductive material through which the electric charges can move.
The force that causes electrons to move in an electric current is measured in volts, which is the unit of electrical potential difference. The flow of electrons is driven by this voltage, creating the current in the circuit.
In solid conductors, electric current is the flow of electrons moving through the material. These electrons move in a coordinated manner in response to an applied electric field, creating the flow of current.
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
