Scientific explanation of working of Electrical Products
October 16th, 2009
The electrical materials represent the actual parts or the elements that are used in order to make any electrical products from the small house circuit to the large industrial plant. Such materials consist of movable electric ions. To conduct electrical material there are several options available.
Find out, how it scientifically works. Neutrally charged atom has similar numbers of protons and electrons in nucleus and orbit consecutively. The number will not always mean that the low energy levels will fill up when the electrons will get close to the atom’s nucleus.
The solids that are made of these electrical materials will tend to usually have an energy band that will always be only filled partly with electrons. Electrons can easily move from one atom to the other, because they will not transit to a next energy level. Metals for instance iron, copper, silver and aluminum will need very low energy for transportation of electron in energy band and that’s why the metals are electrical conductor.
In some electrical materials, the gap in the energy band is so small if it is compared with the general thermal energy that is available per the atom. This will mean that the random thermal motions will cause the atoms and the electrons to move around, in order to provide a few electrons with the needed energy to jump the actual gap. It creates same number of electrons and hole in the conduction and valance band consecutively. The ions that are free charged ones will conduct in material after applying to an electrical field.
The actual motions of the charges will also create some electromagnetic field around the electric conductor that will exert a radial mechanical force that will squeeze the electric conductor.
In some materials thermal & electrical conductivity both is present (for instance, electrical conductors are thermal & electrically active, which stand for a double “asset”). However, many of the electrical metals which are electrical ones will not have thermal proprieties, so there is no such general rule that electrical conduit should have both of the properties.

Electrical Engineering Senior Project at OSU
January 9th, 2009
We built a device capable of reading the power consumption of devices, displaying the measurements on the devices LCD display and wirelessly transmitting the data to a PC for data logging.
This was one of the most memorable and valuable classes I took from OSU and actually had it recorded by our professor. The course focused on pairing up students with different specialized areas in Engineering to work together and build a working Power Meter device. Found this video while searching through some old school data during the holidays.

Electrical and Computer Engineering at UMD!!!
January 2nd, 2009
This was made for a school project. It turned out pretty good. Not very exciting, but then again Electrical Engineering isn’t a very exciting major…..
