Electricity is not a substance, but the behavior of matter

In short: We often speak of electricity as if it were a fluid flowing through wires like water in a pipe. In reality, it is a fundamental property of matter itself—the movement or accumulation of tiny particles that govern how everything in our universe interacts.

At its most basic level, electricity is the phenomenon associated with stationary or moving electric charges. These charges are not unique to electrical devices; they are a fundamental property of all matter. The primary particle involved in these phenomena is the electron, which carries a negative charge by convention. Whether it is the spark from a static shock or the power lighting your home, the underlying mechanism is the accumulation or motion of these electrons.

The study of electricity is divided into two main branches based on whether those charges are moving. Electrostatics deals with phenomena that occur when no moving charges are present—essentially when a system has reached a state of static equilibrium. Because the electric force is extremely strong, charges reach these positions rapidly. In contrast, other forms of electricity involve the continuous flow of electrons through conductors.

You can see this interplay in everyday life: when you rub two insulators together in dry air, electrons are transferred from one body to another. One object loses electrons and becomes positively charged, while the other gains them and becomes negatively charged. This creates an attractive force between them described by Coulomb’s law. Understanding these movements is essential for grasping more complex concepts like voltage, current, and resistance, which serve as the foundation for modern power generation.

While many educational models simplify how electrons behave within atoms—such as using 'shells' to describe their location—it is important to remember that electricity is a study of behavior rather than just particle physics. By understanding how these charges distribute across conductors and insulators, we can calculate electric fields and determine how energy is stored in devices like capacitors.
