    Experiment
In summary, Faraday's experiment involved discovering the relationship between the amount of electricity (F) needed to decompose 1 gram-ionic weight of monovalent ions and Avogadro's number (N) and the charge of an electron (e). This led to the concept of the Faraday Constant, which is approximately 96500 C/mol. This is different from the unit of capacitance, Farad (F), which is measured in Coulombs per Volt. The statement about decomposing ions refers to the amount of charge (N*e coulombs) needed for this process, known as a Faraday.

my book writes about faraday's experiment, and I am totally clueless about this statement:

Faraday discovered that the same quanty of electricty, F, called the faraday and equal to about 96500C, always decomposes 1 gram-ionic weight of monovalet ions.

so he got some formula F=Ne, which N is avorgadro's number and e is the charge of an electron. but how does one farad = N e equate from the previous statement that my book made?

The statement is not 1 Farad = Ne Coulombs. It's 1 Faraday = Ne. A monovalent ion is an ion which has one single positive or negative charge. Therefore, a mole of ions with + or - charge will have N*e coulombs of charge. This unit is called a Faraday, but is better known as the Faraday Constant, which is roughly 96500 C/mol.

A Farad is a unit of capacitance, and is mesured in Coulombs per Volt. In this case, Q = CV, and the Farad has the letter F, which is why I think you're getting confused.

Edit to make it more clear: A farad UNIT is denoted by [F], but Faraday's Constant is just F. It is much like how we denote capacitance the value by the letter C (as in Q = CV), but the unit [C] is a Couloumb. They are different and shouldn't be confused.

what does it mean when it says " decomposes 1 gram-ionic weight of monovalet ions"?
 

1. What was Faraday's experiment?

Faraday's experiment was a series of experiments conducted by scientist Michael Faraday in the 1830s to study the relationship between electricity and magnetism. He discovered that a changing magnetic field could induce an electric current in a wire, and vice versa.

2. What materials did Faraday use in his experiment?

Faraday's experiment used a copper wire, a magnet, and a battery. He also used an apparatus called a galvanometer to measure the electric current produced.

3. What were the key findings of Faraday's experiment?

Faraday's experiment demonstrated that a changing magnetic field can induce an electric current in a wire, and this phenomenon is known as electromagnetic induction. He also found that the strength of the induced current depends on the strength of the magnetic field and the speed at which it changes.

4. How did Faraday's experiment contribute to the development of modern technology?

Faraday's experiment laid the foundation for the development of electric generators and motors, which are essential components in modern technology. It also helped scientists understand the relationship between electricity and magnetism, leading to further advancements in technology and the development of electromagnetic theory.

5. Why is Faraday's experiment still important today?

Faraday's experiment is still relevant today as it is the basis for many technological advancements, such as power generation, electric motors, and electromagnetic devices. It also serves as a fundamental concept in physics, and its principles are used in various fields, including engineering, medicine, and telecommunications.
