# Electronic / Electrical Unit Definitions

### - definitions for popular electrical or electronic units including the volt, amp, coulomb,farad, etc. . . . .

### In this section

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:

The definition for a newton is that force which gives a mass of one kilogram an acceleration of one metre per second squared.*Newton:*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.*Joule:*The definition for a watt is one joule per second*Watt:*A coulomb is the quantity of electricity transported in one second by a current of one ampere.*Coulomb:*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*Volt:*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.*Farad:*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.*Ohm:*A Hertz is the frequency of a periodic phenomenon of which the time period is one second.*Hertz:*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.*Weber:*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.*Henry:*
