JordanPotential difference is the difference in electric potential energy between two points in a circuit. It is measured in volts and represents the work done in moving a unit charge across the points. Electro motive force (EMF) is the energy per unit charge supplied by a source, like a battery or generator, to move charge around a circuit. It is also measured in volts and represents the energy input provided by the source.

What force makes electrons move?
Electrons move in response to an electric force, which is generated by a difference in electric potential. This force causes electrons to flow from areas of high potential (positive) to areas of low potential (negative), creating an electric current.
What is used to measure how strongly the electrons in a wire are pushed?
Voltage is often referred to as Electro-Motive Force, or EMF. It is what causes current to flow in a conductor. Also called volt.
A difference between electric forces and gravitational forces is that electrical forces include?
Electrical forces include both attractive and repulsive interactions between charged particles, whereas gravitational forces are always attractive between objects with mass. Additionally, electric forces are much stronger than gravitational forces, but they have a shorter range.
What determine the direction of flow of charge?
The direction of flow of charge is determined by the electric field present in a circuit. Charge will flow from areas of higher potential energy to lower potential energy, following the direction of the electric field.
What two factors determine the potential energy of an elevated object?
The potential energy of an elevated object is determined by its height above the reference point and the force of gravity acting on it. The higher the object is lifted and the greater the force of gravity, the more potential energy it has.
