Benjamin Franklin was a Founding Father of the United States and a polymath who made significant contributions to the advancement of electricity. He is credited with coining several electrical terms that are still used today, such as charge, positive, negative, and conductor. Franklin's experiments with electricity led him to discover that it consisted of a common element, which he termed electric fire. He also understood electricity to be fluid-like and capable of passing from one body to another without destruction. In addition to his electrical work, Franklin was also an inventor, creating the Franklin stove, improving the U.S. postal system, and starting America's first lending library.

'Battery'
Benjamin Franklin (1706-1790) was an American writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher. He is credited with coining the term "battery" to describe a group of electrical devices.
In 1748, Franklin described multiple Leyden jars by analogy to a battery of cannon, borrowing the term from the military, which refers to weapons functioning together. A Leyden jar, dating from around 1749, is a primitive battery with charge within it. Franklin discovered that by linking multiple jars together, he could increase the amount of charge they could store. He called this new assembly of Leyden jars a "battery," and he is credited as being the first to use the term in relation to electricity.
Franklin's work with Leyden jars and his coining of the term "battery" were significant contributions to the field of electricity. He also conducted other experiments that changed people's understanding of electricity, such as his famous kite experiment, which demonstrated that lightning is a form of electrical discharge. Franklin's work became the basis for the single fluid theory of electricity, which states that electricity is a common element that flows between bodies and is never destroyed.
The term "battery" has since been used to describe a variety of electrical devices, including the electric battery invented by Alessandro Volta in the late 18th and early 19th centuries. Volta's work built upon Franklin's discoveries and further advanced our understanding of electricity. Today, batteries are an integral part of modern technology, powering everything from cars to smartphones.

'Charge'
Benjamin Franklin is known for his experiments with electricity, which changed people's understanding of the subject. One of his most famous experiments involved flying a kite in a thunderstorm, which demonstrated the electrical nature of lightning.
Franklin also created a new vocabulary to describe electrical phenomena. One of the terms he coined was "charge". He discovered that positive charges resided on one side of a Leyden jar and negative charges on the other. By linking multiple jars together, he could increase the amount of charge they could store. He called this new assembly of Leyden jars a "battery", and he is credited with being the first to use this term in relation to electricity.
Franklin understood that electricity was a "common element" which he named "electric fire". It was a fluid that passed from one body to another but was never destroyed. In a letter to Peter Collinson, Franklin wrote:
> "We say B (and other Bodies alike circumstanced) are electricised positively; A negatively; Or rather B is electricised plus and A minus ... These terms we may use till philosophers give us better."
Franklin's work became the basis for the single fluid theory. When something is being charged, such as a car battery, electricity flows from a positive body, with an excess charge, to a negative body, which has a deficit.

'Positive' and 'negative'
Benjamin Franklin is known for his experiments with electricity, which changed people's understanding of the subject. Before Franklin, it was thought that electricity consisted of two opposing forces. Franklin discovered that electricity was a "common element", which he named "electric fire". He described this substance as a fluid that passed from one body to another without being destroyed.
Franklin also created a new vocabulary to describe electrical phenomena. The terms "charge", "positive", "negative", and "conductor" were coined by him. The familiar markings on batteries, a (+) at one end and a (-) at the other, are also Franklin's invention. He called an assembly of Leyden jars a "battery", and he is credited as being the first to use the term in relation to electricity.
Franklin's experiments with Leyden jars and kites demonstrated the connection between lightning and electricity. He discovered that lightning was electricity, and he invented lightning rods to redirect electricity away from buildings, thus protecting them from lightning strikes.
Franklin's work with electricity was just one aspect of his wide-ranging interests and talents. He was also a writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher. He helped draft the Declaration of Independence and contributed to the founding of the United States of America.

'Electric fire'
Benjamin Franklin was a Founding Father of the United States and a man of many talents. He was a diplomat, politician, printer, publisher, political philosopher, and scientist. He made significant contributions to the advancement of knowledge in various fields, including media, community institutions, exact sciences, and political science.
One of his most notable contributions was in the field of electricity. Franklin conducted experiments that changed people's understanding of electricity. Before Franklin, it was believed that electricity consisted of two opposing forces. However, Franklin's experiments led him to discover that electricity consisted of a "common element," which he named "electric fire." He described electricity as a fluid that passed from one body to another without being destroyed. In his correspondence with Peter Collinson, Franklin wrote about the need for new terms to describe his findings:
> "I feel a Want of Terms here and doubt much whether I shall be able to make this intelligible... These terms we may use till philosophers give us better."
Franklin's experiments with "electric fire" or electricity included his famous kite experiment in 1752. He flew a kite during a thunderstorm and demonstrated that lightning was a form of electric fire or electricity. He also invented the lightning rod, which redirects electricity away from buildings to prevent them from catching fire.
Franklin also coined several electrical terms that are still in use today, such as "charge," "positive," "negative," "conductor," and "battery." He is credited with creating a new vocabulary to describe electric phenomena, and his work laid the foundation for modern electrical understanding and technology.

'Common element'
Benjamin Franklin is known for his experiments with electricity, which changed people's understanding of the phenomenon. Before Franklin, it was thought that electricity consisted of two opposing forces. Franklin, however, discovered that electricity consisted of a "common element", which he named "electric fire". He described this element as a fluid that passed from one body to another but was never destroyed.
In a letter to Peter Collinson, Franklin wrote:
> "Fire only circulates. Hence have arisen some new items among us. We say B (and other Bodies alike circumstanced) are electricised positively; A negatively; Or rather B is electricised plus and A minus ... These terms we may use till philosophers give us better ones."
Franklin's work became the basis for the single fluid theory. He also created a new vocabulary to describe electrical phenomena, coining terms such as "charge", "positive", "negative", and "conductor", which are still used today.
Franklin's experiments with electricity included his famous kite experiment, in which he demonstrated that lightning was a form of electricity. He also invented the lightning rod, which could redirect electricity away from buildings to prevent them from burning down. For his work, Franklin received the prestigious Copley Medal from the Royal Society in 1753.
