The electric field from a positive charge points away from the charge; the electric field from a negative charge points toward the charge. Like the electric force, the electric field E is a vector. ... The one big difference between gravity and electricity is that m, the mass, is always positive, while q, the charge,

Like gravity, an electric force field, which is associated with ... Going on with the development of electrical force, the affect of a particle between one or more field surfaces can now be developed. ... The change in potential energy is equal to the charge times the difference between the voltage at 'A' and the voltage at 'B'.
