Want this question answered?
As long as there is any electric potential, charges continue moving around, until everything is balanced.
The device that uses chemical energy to give charges electric potential energy is a battery because it uses chemical energy which gives off potential electric charges.
A conductor.
it is magnetic force
No charges have to be present.

flow of electricity through a conductor are electric charges

A conductor.
There is no electric field inside a conductor.Otherwise, the charges in the conductor would move.Charges exist only on the surface of a conductor.Otherwise, there would be electric fields inside.All points of a conductor are at the same potential.Since DV=-EDx, since E=0, the potential must be constant.
False... That is called an electrical current.
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
when we hit someone, he generates electric charges &he begins to dance & sing songsss.
it is formed by the electric discharge b/w clouds & the earth. during days of thunderstorm water droplets in clouds acquire charges due to polarisation.Hence it is at a higher potential.Whereas earth in comparison to it is at a much lower potential .So,charge flows from clouds to abnormally air is a non conductor of electricity , but with high potential difference, air gets polarised.Thus becomes a good conductor & charges flows down to earth.
I know that one is a Conductor
it is magnetic force
That means that no electric forces act on charges, and therefore, charges won't move around.
