Electricity is a physical phenomena involving positive and negative charge. When these charges are in motion they may produce heat, light and magnetism. When charges are not in motion, static electricity can manifests itself as a force such as clothes clinging to each other when they are removed from a dryer. A simple stationary system of a
single positive ion and a single negative ion (or electron) separated by large
distance with respect to their size ( a meter for example) will have a E field
associated with them. Along the axis connecting the two ions the E vector points
directly from the positive ion towards the negative ion. At this
theoretical point in time there is no H field. The E field will cause the charge
particles to move towards each other. This relative motion of positive and
negative charge is the simplest example of current. Associated with this
tiny current a magnetic or H field will exist. The motion of the positive charge
will be in the direction of the E field and the negative charge will move in the
opposite direction of the E field. Current by definition flows in the direction
of the E field. It follows that positive charge moves in the direction of
current and negative charge moves opposite to the current. Practical Application of above: When I studied electronics in the military, I learned the electron flow version of electronics. When I studied Physics in college, we used conventional current flow. This made remembering things like the left hand rule and right rules for curl etc. very confusing. Thus, I recommend not buying an electron flow version of a text and sticking with conventional current flow.

Virtual Circuit Kits: The Internet provides you with all the graphics and text about electronics that one can imagine. My site and e-books are special, because they provide not only free books, but the books include FREE virtual circuits to observe and troubleshoot. You get virtual circuits with out the expense of Brick and Mortar bread boards. Industry does not need technicians that have simply read about electronics circuits, that is why electronics schools have laboratories in addition to classrooms. I provide laboratory manuals combined with virtual circuits for you to troubleshoot. That makes this site and its free downloads different, if not unique. Please bookmark my site and download some or all of my free e-books and simulations.
Also Included as part of our Free System Troubleshooting learning method are: 1. Meter Math (Click here) Troubleshooting Numeric Systems. 2. JavaScript for scientific Calculations (Click here) I teach you how to program and perform electronic calculations simultaneously. 3. Electronic Concepts our best free e-Book (Click here) For engineers and technicians. New! ( Fall 2007) Force Fields. A E&M physics primer for electronics students.
