Effect of electron discrete nature on current density

Coulomb’s law states that the current that flows through a wire is proportional to the applied voltage. For sure there are many physical effects (linear and non-linear) that participates in the ...

Conductor interaction with single battery terminal

What really is happening inside a wire and inside battery when I connect one end of wire to the one terminal of battery but not the other (open circuit )? Questions: If I connect to the '+' ...

Why does high voltage imply a high “pushing force” on electrons?

Another word for potential difference, is apparently, "voltage drop", although I've heard potential difference be interchangeable with just voltage, as well, a bit confusingly. However, if I ...

What happens when a conductor gains potential, but is not completing a circuit

I asked this on the physics stack initially, but I think it could also be appropriate here. I am not confused about how a conductor gains the same potential as the lead it is connected to (in the ...

Semiconductor physics, effective mass calculations, band edge. vs. DOS vs cyclotron resonance

I am trying to understand effective mass for electron carriers in the conduction band as found in experiments. I am using the equations in a simulator. The simulator models power mosfets from -85C to ...

How does the hot point-probe test affect p-type semiconductors?

In an n-type semiconductor if you place a hot probe close to a cold metal probe, the average thermal velocity of electrons near the hot probe increases which leads to a net electron motion from the ...

Theory : High voltage but low current

I read that : A generator products electrons that it sends into wire The electron motion is due to the repulsive behavior between electrons So to increase the voltage (speed of electrons?), ...
