Electricity is the set of physical phenomena associated with the presence of electric charge. Although initially considered a phenomenon separate to magnetism, since the development of Maxwell's Equations both are recognized as part of a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. In addition, electricity is at the heart of many modern technologies.

The presence of an electric charge, which can be either positive or negative, produces an electric field. On the other hand, the movement of electric charges, which is known as electric current, produces a magnetic field.

When a charge is placed in a location with non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's Law. Thus, if that charge were to move, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positive charge from an arbitrarily chosen reference point to that point without any acceleration and is typically measured in Volts.
