A current.
"current"
Fe = kq1q2 / r2 where k = 1/4πε, (ε is the electrical permittivity of free space), q1 and q2 are the two point charges, and r is the distance between the point charges. Therefore, electrical force varies inversely with distance, or to be more specific, they follow an inverse-square relationship.
The electrical conductor is important because it transfers electricity from one point to another.
Yes.
Yes, that's basically what "electrical current" means.
The system of two point charges plus q and -q constitutes an electric dipole.In the case of an electric dipole ,the resultant field is parallel to the line joining the two charges at 1.any point on the line joining the charges 2.any point on the perpendicular bisector of the line joining the two charges.
"voltage" (also referred to as 'potential')
Current is created when electrical charges move through a wire or other conductor. It can be produced by rotating magnetic fields (as in a generator) or by connecting a source of higher electrical potential (charge) to one of lower electrical potential, which can cause the movement of charges from one point to another.
An Electrical wire is used to flow the electrons from one point another point . Copper or aluminum is insulated with polythine is called wire
An electrical circuit is a path which electrons from a current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". ---Nerd

The Force on a point charge from another point charge is along the Line connecting between the two charges. The direction will be towards the point charge if the two charges are different and away if they are same.Now if you collection of Charges then it is vector sum of force due to each charge.
A1 is a termination point on a contactor it is an alseriery going to another point.
Man-made permanent magnets are not so different from naturally-occurring magnets.In the case of a permanent magnet, electrical charges are irrelevant. The magnet may, or may not, have an electrical charge, but that doesn't affect the magnetism. An electromagnet works by electrical currents, which is a flow of charges. The electromagnet, however, doesn't need to have any net charge. In other words, any charge would go in at one point of the magnet but an equivalent charge would go back out at some other point.
The equation for an electrical force between two point charges: F = k*q1*q2/r^2, where F = the attractive or repulsive electrical force [N] k = electrical constant = 8.99x109 [N m2 C-2] q1 and q2 are the magnitude of the two point charges in question [C] r = the separation between the two point charges [m] ------------------------------------------------------------------------------------ Since q1 = 3 [C] and q2 = -3 [C], F is negative in sign --> attractive force. Rearranging the force expression, we have r = sqrt {k*q1*q2/F} = sqrt {-8.99x109*3*3/-1} = 2.844x105 [m]. ==============================
Yes, that's basically what "electrical current" means.
