How can you experimentally distinguish an electric field from a gravitational field?
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.
What unit measure the force that makes electron move in a electric current?
Power
Current is produced when charges are accelerated by an electric field to move to a position of lower what?
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
Why electric field lines are continuous?
Electric field lines are continuos because they move from +ve to -ve it means they move a particular point from A to B if they move from A to B and then to A then this path way is called discontinuous
What actually moves when an electric current flow?
Electrons move in electron current flow.
If a stationary electron sat inside a stationary electric field would the electric field cause the electron to move?
Yes. Stationary electric (electrostatic) fields will act on each other and a force will be developed. If you had a standing electric field and could "beam in" an electron (a la Star Trek), the electron would react at once and move either toward a positive field source or away from a negative field source. The electron would know the field was there the instant it appeared.
What is classical free electron theory of metal?
Classical free electron theory is modeled by drude - Lorentz to explian elctrical conductivity in metals. According to this free electron in a metal (valence electron) move randdomly at room temperature and these free electron are drifted in opposite to the direection of the applied electric field. This is repsonsible for the conduction. Here all the free elctron are are considered as equal in all aspect.
Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field

If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
Mobility in terms of hall effects?
Mobility means how quickly an electron can move through a metal or semiconductor when an electric field is applied.
Why electron does not fall in one of the charged plate of opposite polarity when moving inside electric field?
An electron, being negatively charged, will move towards positively charged plates.
Why electron move in circular path around the nucleus?
because the electric field of the nucleolus is radially symmetrical. And if you really want to get picky, the electron doesn't move in a circle but occupies a spherical probability continuum with indeterminable position and velocity.
Which subatomic particle is free to move?
Electrons are free to move within an atom and between atoms, making them the subatomic particles that can easily move. Electrons are negatively charged and are responsible for the flow of electric current in conductive materials.
Does everything have a magnetic field?
No. Magnetic field arises due to a specific arrangement of electrons inside a substance. Hmm, I'd guess Yes. When there is electricity, there is a magnetic filed. Whenever an electron moves, not only does its electric field move, but also a magnetic field may be appreciated (if you are not moving with the electric field). OK, so gravity doesn't have a magnetic field.
