Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
electric charge: coulomb (C) heat: joule (J) Reactive Power: volt-ampere reactive (var) electric charge: coulomb (C) electrical resistance: ohm (Ω) Ricci tensor: reciprocal square meter (m −2) radiancy: meter per second: gas constant: joule per mole per kelvin (J⋅mol −1 ⋅K −1) radius vector (position)
Derived quantities can be expressed in terms of the base quantities. Note that neither the names nor the symbols used for the physical quantities are international standards. Some quantities are known as several different names such as the magnetic B-field which is known as the magnetic flux density , the magnetic induction or simply as the ...

This is a list of well-known dimensionless quantities illustrating their variety of forms and applications. The tables also include pure numbers , dimensionless ratios, or dimensionless physical constants ; these topics are discussed in the article.
In other words, the quantities of different elements deposited by a given amount of electricity are in the ratio of their chemical equivalent weights. [ 32 ] An important aspect of the second law of electrolysis is electroplating , which together with the first law of electrolysis has a significant number of applications in industry, as when ...
Once upon a time, the symbol E (for electromotive force) was used to designate voltages. Then, every student learned the phrase ELI the ICE man as a reminder that: For an inductive (L) circuit, the EMF (E) is ahead of the current (I)
High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
