What else can I help you with?
When does current flow through a conductor?
When a voltage is applied across it.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.
What causes an electric current?
An electric current is caused by the flow of charged particles, typically electrons, through a conductor. When there is a potential difference (voltage) applied across a conductor, the free electrons will move in response to this voltage, creating a flow of electric current.
What is present in a conductor when an electrical charge moves through it?
In a conductor, free electrons are present that can move when an electrical charge is applied. These free electrons are responsible for the flow of current through the conductor.
What is the steady flow of electrons through a conductor?
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
How does current flow in a conductor?
Current flows in a conductor when there is a potential difference applied across it, creating an electric field that causes the movement of free electrons in the conductor. The electrons flow from the negative terminal to the positive terminal of the voltage source.
Is a depletion region a good conductor?
No, a depletion region is not a good conductor. It is an insulating region formed in a semiconductor material when a voltage is applied, creating a barrier to the flow of current.
What is the force which drives an electric current through a conductor?
An electric current is driven through a conductor by the force of voltage or potential difference applied across the ends of the conductor. This force pushes the free electrons in the conductor, causing them to move in a particular direction, thus creating an electric current flow.
Why is it easy to create a current in a conductor and not in an insulator?
It is easier to create a current in a conductor because conductors have free-flowing electrons that can move easily when a voltage is applied, allowing for the flow of current. Insulators, on the other hand, have tightly bound electrons that do not move freely, making it more difficult to establish a current flow in them.
How is an electric current produced and what factors influence its generation?
An electric current is produced when electrons flow through a conductor, such as a wire. Factors that influence the generation of an electric current include the voltage applied, the resistance of the conductor, and the presence of a closed circuit.
Is it true that the flow of charges through material is electric current?
Yes, the flow of electric charges through a material is known as electric current. This flow of charges typically involves the movement of electrons in a conductor when a voltage is applied across it.
