The principles of energy storage, electrical charge, and potential difference are vital components in the field of electricity and magnetism, a subfield of physics. Energy storage refers to the methods by which energy is stored for later use. The electrical charge is a fundamental property of matter that results in electromagnetic interactions. The potential difference, also known as voltage, is the work done per unit charge. These concepts are interconnected in several ways, one of which is the calculation of the energy stored in a system given the electrical charge and potential difference. This tutorial will explain these principles and their interconnectedness in more detail.

The energy (E) stored in a system can be calculated from the potential difference (V) and the electrical charge (Q) with the following formula:
The formula for energy storage was derived from fundamental principles of physics. It's a direct result of the definition of potential difference or voltage and the principle of energy conservation. While it's difficult to attribute this formula to a single individual, the principles on which it relies were contributed to by many scientists over the years, including Charles-Augustin de Coulomb, André-Marie Ampère, and Michael Faraday.
The concept of energy storage, electrical charge, and potential difference is applied in many everyday technologies. For instance, rechargeable batteries, such as those in electric cars or mobile phones, store energy chemically and release it as electric power. Understanding these principles allows us to calculate the energy a battery can deliver given its voltage and charge capacity.
Charles-Augustin de Coulomb, André-Marie Ampère, and Michael Faraday were key figures in developing the understanding of electrical charge and potential difference. Their experiments and discoveries laid the groundwork for the development of modern electric and magnetic theory.
The concepts of energy storage, electrical charge, and potential difference are integral to understanding many natural phenomena and technological applications. These principles, embedded in the field of electricity and magnetism, have shaped our understanding of the world, catalyzed technological advancements, and continue to influence new discoveries and innovations.
