Which energy of electrons make any electrical instrument work?

The energy of electrons that makes any electrical instrument work is primarily known as electromotive force (EMF). EMF is the electrical potential difference or voltage between two points in an electrical circuit. It enables the flow of charged particles, such as electrons, through the circuit and is responsible for generating electric current.
Electromotive force is generated in several ways. One way is through the chemical energy stored in batteries or fuel cells. The chemical reactions in these energy sources convert chemical energy into electrical energy, which is then stored in the battery's terminals. When a potential difference is applied across the battery's terminals, electrons are pushed from one terminal to the other, creating an electric current.
Another source of electromotive force is electromagnetic induction. When a magnetic field changes, it generates an EMF across the air gap in a coil. This EMF creates a flow of electrons, resulting in an electric current. For example, in an alternating current (AC) generator, a stationary magnetic field is created by an electromagnet. When an alternating current is applied to the stator windings, it creates an EMF, which in turn induces an electric current in the rotating magnetic field.
