No. In a good conductor you simply need less potential difference than in a bad conductor, to get the same current. But if you have zero voltage, you will also have zero current. Unless you have a superconductor (zero resistance), and the current is already flowing.
If a compass is suspended next to a conductor that is not carrying an electron flow, there will be no effect on the compass. The flow of electrons is what creates a magnetic field, so without electron flow in the conductor, there will be no interaction with the compass needle.
If the EMF or voltage source is removed from a conductor, the electron flow will eventually stop. This is because the EMF or voltage source provides the force that drives the movement of electrons through the conductor. Without this force, the electrons will no longer be pushed and will come to a rest.
Keeps the current in the conductor. Without the insulation on a conductor the current can and will leave the intended path in the electrical circuit if it comes in contact with some other conductive path if there is a difference of potential.
When a voltage is applied across a conductor, it creates an electric field that exerts a force on the electrons, causing them to move. The electrons repel each other due to their negative charges, so when one electron moves, it pushes others along in a chain reaction. This process allows electrons to flow through the conductor without directly touching each other.
A hydrogen atom is only a proton and an electron. Beyond that the neutron seems to keep the nucleus together and stable. Maybe a better question is, "What is the difference between a hydrogen atom without an electron and a proton?"
A conductor
Thermal conductor means: process by electrons in the solid materials transfere heat energy when the particles collides each others because of the temperature difference between two points without moving the particles itself from its origion position .
The maximum amount of current a conductor can carry continuously without exceeding its temperature rating is typically determined by the conductor's ampacity rating, which is based on factors such as the conductor material, insulation type, and ambient temperature. It is important to adhere to these ampacity ratings to prevent overheating of the conductor.
Will proper staining and the right organism the nucleus of a cell can be seen without an electron microscope.
A perfect conductor would have infinite thermal conductivity, meaning it can effectively transfer heat instantaneously without any temperature difference across its surface. In reality, perfect conductors do not exist, but materials such as metals like silver and copper have high thermal conductivity values relative to other materials.
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
No, an electron cannot remain in an excited state without additional energy input. Excited states are temporary and the electron will eventually return to its ground state, releasing the energy it absorbed as photons.
