What is a Capacitor?
A capacitor is an electronic component that stores electrical energy by separating positive and negative charges on two conductive plates. These plates are separated by an insulating material (called a dielectric).
What is Capacitance?
Capacitance is the measure of how much electric charge a capacitor can store per unit of voltage applied across its plates. It is expressed in farads (F) and depends on the size of the plates, the distance between them, and the type of dielectric used.

Ewald Georg von Kleist (1700–1748)
Ewald Georg von Kleist was one of the first to discover that electric charge could be stored using a glass jar partially filled with water and a conducting nail. Around 1745, he unintentionally created a primitive capacitor, later known as the Leyden jar, while experimenting with electricity and electrostatic discharge. His work marked a key turning point in understanding charge storage.

Pieter van Musschenbroek (1692–1761)
Pieter van Musschenbroek independently invented the Leyden jar between 1745 and 1746 at Leiden University. His version was more refined and became widely known across Europe. He helped establish the jar as a reproducible and effective method for storing electric charge, playing a vital role in early electrostatics.

Benjamin Franklin (1706–1790)
Benjamin Franklin conducted extensive studies in electrostatics during the 1740s and 1750s. He coined the term “battery” to describe an array of Leyden jars and explored how electric charge accumulated on surfaces. His work advanced the conceptual understanding of positive and negative charge and helped shift scientific views toward a more unified theory of electricity.
