Electrical conductivity One to five percent of the caffeine molecule dissociates in water‚ proving that the compound is a weak electrolyte. A substance that completely dissociates in a solution‚ such as water‚ is considered an electrolyte and can therefore conduct electricity. This dissociation is caused by the atoms’ minimal nuclear charge‚ allowing the substance to break apart entirely into its ions. Ions are mobile‚ which induces a current and contributes to the substance’s high electrical conductivity

electricity moves better through thick wires or through thin wires. For this experiment I used two size D batteries‚ two flashlight bulbs‚ one 6.5 inch thin steel wool piece‚ one 6.5 inch thick steel wool piece‚ two 2 inch pieces of straw‚ and some electrical tape. Steel wool is a material made from thin fibers of steel made into a pad. (http://www.wisegeek.com/l-what-is-steel-wool.htm) There are many uses for steel wool. It can be used for sanding furniture‚ removing paint finishes; it can be used

well educated electrical engineer and promote my existing career in related industries. As a high school student we had an electricity lesson in which we had to make a simple motor using wooden board‚ nails and coated wire and battery. After assembling the materials when I connected the system to the 3 volt battery‚ the rotor‚ made by winded nail‚ started rotating suddenly .it was incredible for me and I always remember it as a dream. This phenomenon motivated me to opt electrical engineering for
