A material that hinders the passage of electric charge is?
An insulator is a material that hinders the passage of electric charge. Insulators have high electrical resistance, which prevents the flow of electric current through them. Examples of insulating materials include rubber, glass, and plastic.
How can one determine the charge density from an electric field?
To determine the charge density from an electric field, you can use the formula: charge density electric field strength / (2 epsilon), where epsilon is the permittivity of the material. This formula relates the electric field strength to the charge density of the material.
What is the relationship between surface current density and the flow of electric charge in a conducting material?
Surface current density refers to the flow of electric charge per unit area on the surface of a conducting material. It is directly related to the flow of electric charge within the material, as the surface current density is a result of the movement of charge carriers within the material. In other words, the higher the surface current density, the greater the flow of electric charge within the conducting material.
Why is foam a good conductor?
Foam is not a good conductor; in fact, it is an insulator. Foam is made up of many small pockets of gas trapped within a solid or liquid material, which greatly hinders the flow of electric charge, making it a poor conductor of electricity.
When can a static electric field arise?
A static electric field can arise when there is a buildup of electric charge in a stationary object or material.

What is the movement of electrical charge on a material called?
The movement of electrical charge on a material is called electric current. It is defined as the flow of electric charge through a medium, such as a wire, in response to an electric field.

How does a material acquire a positive electric charge?
By losing electrons.
What is the continuous flow of charge through a material.?
Electric Current.
When an electric charge moves through a conductor there is an electric in the conductor?
When an electric charge moves through a conductor, an electric current is generated in the conductor. The flow of electrons creates a flow of current in the conductor, which is the movement of electric charge through the material.
When can a static electric field arise?
A static electric field can arise when there is a buildup of electric charge in a stationary object or material.
What is the device used to store an electric charge?
A capacitor is a device used to store an electric charge. It consists of two conductive plates separated by an insulating material, typically air or a dielectric material. When a voltage is applied across the plates, one plate accumulates positive charge while the other accumulates negative charge, storing energy in an electric field.
How does the presence of a charge inside a conductor affect the distribution of electric potential within the material?
The presence of a charge inside a conductor affects the distribution of electric potential by causing the charges to redistribute themselves in such a way that the electric potential is the same throughout the material. This is known as electrostatic equilibrium.
What is a material that readily allows electric charges to pass through it?
Copper is very good conductor of electric charge. That is why it is invariably used in the electric motors.
