From my understand, electric field is the force emitting from a charge. This means that if a charge was placed in the vicinity of the charge that was emitting the field of force, that charge placed would experience a force from it. How does potential energy differ from this? I understand that potential energy is in joules, meaning it's work. So does that mean it's the amount of work being done on the charge? Say there is a positive charge there and a negative charged was placed x distance away from it. Would calculating the potential energy from that distance be the amount of work done to bring the two charges together? In this example it would be the positive charge moving towards the negative charge? What would happen if it was two of the same charges in that it would experience an repulsive force, say two positive charges? In a battery, the amount of volts it provides is the amount of work per coulomb? So it would be providing 1.5 joules per 6.24*10^8 electrons?
