Electrical Fundamentals

the first things we must know, before start to learning electronics and it's application is electrical fundamentals.
in this sections we start with learning about units, charge and current, voltage, energy and power and ohm's law and kirchoff's laws.Ok, lets begin.
Fundamental Units
Basic Units are units which are used as reference in lowering derived unit  .Fundamental units is the units that we now use to describe such things as length, mass and time are standardized within the International System of Units. This SI system is based upon the seven fundamental units (see table 1.1).

Derived Units

Derived Units are units derived from the basic unit. All other units are derived from these seven fundamental units. these derived units generally have their own names and those commonly encountered in electrical circuits are summarized in table 1.2 together with the physical quantities to which they relate.

Electrical Units and Symbols

You will find that the following units and symbols are commonly encountered in electrical circuits. it is important to get to know these units and also be able to recognize their abbreviations and symbols (see table 1.3).

Multiples and Sub-multiple
Unfortunately, many of the derived units are somewhat cumbersome for everyday use but we can make life a little easier by using a standard range of multiple and sub-multiple (see Table 1.4)

Welcome

Hi,...!
Currently, developments in the field of informatics and communications have become  very rapidly to changing the world. It's shown by the findings in the field of informatics and communication make the world seemed without limit. access of  information quickly going from various parts of the world. But one thing is not apart from it all is the development of both devices in the field of electronics technology and material technology. Therefore, basic electronics is a matter that should be a concern to a practitioner of electronics as well as academics to understand more about electronics applications such as in the field of informatics and communications.
Some of the following articles would help us understand the basics of electronics. hopefully can be useful for us all.
