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 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 much current flow through 3.5milimeter conductor?
how we decide current throuh conductor
What is the term used for the hindrance a conductor creates to the flow of electric current?
Resistance is the hindrance a conductor creates to the flow of electric current
What is the relation between current and thikness of conductor?
The thicker the conductor, the less the current that will flow through.
What happens to metals as they conduct electricity?
The electrons in a conductor will support the movement of electric current. A conductor is defined as a material with a number of electrons in its makeup that are actually in what is called the conduction band. The conduction band is an energy level where electrons must be to permit conduction in a material. If the minimum energy in the conduction band in a material is such that a lot of electrons in that material are already at or above that level, then these electrons will be available to support current flow. Remember that electron current flow is moving electrons, and it is not about sending an electron into a conductor, like a wire, at one end and getting that same electron out at the other. It is about sending a bunch of them in at one end, and all the electrons already in the conductor move over and a bunch come out the other end. The electrons already in the conduction band within the conductor support current flow in this way.
Does an electric current flow through a material that is conductor or an insulator?
A conductor
What is a pathway for current to flow caled?
conductor
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
What pressure or force that causes current flow through a conductor is caleed?
The pressure or force causing current to flow through a conductor is called voltage.
