How does one Coulomb of charge compare to the charge on an electron? How do you think such a large difference arose historically?
Which came first, and why?
Google
Ampere
What do u mean? ive been reading up on it and cant find anything that relates between them not the charge or anything so i don't get this questiong and plus how would I know how it arose historically. . .
ampere history
This is how I expect you to find the answer. If I were not so kind and generous, I would give you the answer.
Ok found the histroy but I don't see how it relates to the charge of an electron. . . or how ahhhhh.
Coulombs (ampere-seconds) came about when electrical currents were measured at levels that had easily measured observable effects, in laboratories of the 1800's.
The concept of electric charge was first proposed by Benjamin Franklin, nearly a century earlier than that. He looked for measurable effetc in electroscopes, which typically required coulombs of charge.
The charge of a single electron was measured by Millikan and his graduate student Fletcher about 50 years after the discovery of Maxwell's laws of electricity, using the oil drop experient to isolate single electrons in the laboratory.
Look up the charge of the electron and you will find that it is much less than a Coulomb... More than a billion billion times less.
One Coulomb of charge is equal to the charge on approximately 6.24 x 10^18 electrons.
To understand how such a large difference arose historically, we need to delve into the concept of charge and the development of our understanding of electricity.
The fundamental unit of charge is the charge of an electron, represented by the symbol "e". The charge of an electron is approximately -1.6 x 10^-19 Coulombs (C), which means it carries a negative charge.
The concept of charge and the development of electrical theory started in the 18th century with the work of scientists like Benjamin Franklin, Charles-Augustin de Coulomb, and Michael Faraday. Franklin proposed that there are two types of charges, positive and negative, where opposite charges attract each other and like charges repel.
The unit of charge, Coulomb, was named after Charles-Augustin de Coulomb, a French physicist who conducted experiments on electrostatic force. Coulomb's Law describes the force between two electric charges and played a crucial role in the development of our understanding of electricity.
Historically, as scientists conducted more experiments and made more advancements, they discovered that electric charge is quantized, meaning it comes in discrete units. The charge on an electron was determined, and it became the standard unit of charge.
The large difference between one Coulomb and the charge on an electron arises from the fact that macroscopic objects, which we interact with on a daily basis, contain an enormous number of electrons. Each electron carries a relatively small charge, but the total charge of a macroscopic object can be significant due to the vast number of electrons it contains.
So, the discrepancy in charge values between one Coulomb and the charge on an electron is a result of our understanding and observations of charge, electrical experiments, and the quantized nature of charge.
