Voltage, Current, Power and Energy

Let's begin with the very basic concept of Electrical Engineering . We should do this because as we move along, we will use these basic concepts on more complicated applications. The following topics were already taken from our Physics course but for those who already forget it, let's take a short review. The Voltage We all know that Potential Difference between two points is the work done per unit charge when a charge is moved from one point to the other. The defining equation for this is, V = W/Q where : V = the voltage in volts . W= energy in joules . Q = is the charge in coulombs , is always understood to be a positive charge in a conventional way, thus making definite the algebraic sign of the potential difference in any particular case. One volt is defined as the potential difference between points in an electric circuit such that one joule of work must be done to move a charge of one coulomb between the points considered. Since the difference of potential between two

Learning Electrical Engineering

First of all, before I give you the purpose of learning this course. Let me give you a short but comprehensive definition of Electrical Engineering. I just want to assumed that my readers are technical and non-technical people. At least they could understand a bit what the content of this site is all about. Electrical Engineering is an applied science that deals with the study of electricity, electronics and electromagnetism. L.E.E.B.
