Discuss Joule-Thompson effect with relevant examples and formulae. Define the term energy. State and define its SI unit. B)In physics (and in all science) standard units are used to ensure measurement uniformity. Which of the following fictitious units of measuremen...
That group of physical constants which play a fundamental role in the basic theories of physics. These constants include the speed of light in vacuum,c; the magnitude of the charge on the electron,e, which is the fundamental unit of electric charge; the mass of the electron,me; Planck's ...
Electric current is the amount of electric charge passing through a given surface or given point per unit of time. The S.I unit of current is the... Learn more about this topic: Standard Units of Measurement | Overview & Examples
In this system of units the constant k appearing in Coulomb’s law is equal to 1. The cgs unit of charge is the esu, an acronym for the oh-so- clever name electrostatic unit. It is defined such that two charges of 1 esu each, separated by 1 cm, feel a force of 1 dyne: 1...
