Electronic / Electrical Unit Definitions
- definitions for popular electrical or electronic units including the volt, amp, coulomb,farad, etc. . . . .
Units, symbols & constants pages include:
While anyone involved in electronic development, design, manufacturing, service, repair or any other area associated with electronics will have a good idea about the electrical units or electronic units used, definitions of them are sometimes quite useful.
As a result a number of electrical unit definitions or electronic unit definitions have been included below.
These electronic unit definitions are included for some of the most popular items.
Electronic unit definitions
Definitions for the more widely used electrical units are included below:
- Newton: The definition for a newton is that force which gives a mass of one kilogram an acceleration of one metre per second squared.
- Joule: The definition for a joule is the work done when the point of application of a force of one newton is displaced through one metre in the direction of the force.
- Watt: The definition for a watt is one joule per second
- Coulomb: A coulomb is the quantity of electricity transported in one second by a current of one ampere.
- Volt: The definition for a volt is the potential difference between two points of a conductor carrying a constant current of one ampere when the power dissipated in the conductor is one watt
- Farad: One farad is the capacitance between the plates on a capacitor when the quantity of one coulomb of electricity produces a potential difference between the plates on one volt.
- Ohm: The definition of an ohm is the resistance between two points of a conductor when a constant potential difference produces a current of one ampere.
- Hertz: A Hertz is the frequency of a periodic phenomenon of which the time period is one second.
- Weber: A weber is the flux which, linking a circuit of one turn, produces in it an EMF of one volt as it is uniformly reduced in one second.
- Henry: The definition of a henry is the inductance of a closed circuit which produces an EMF of one volt when the current varies uniformly at one ampere per second.
