Resistance in a Conductor: The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. Electrical resistance shares some conceptual parallels with the mechanical notion of friction. The SI unit of electrical resistance is the ohm (Ω).An object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance‚ except

INTRODUCTION Although EEG is designed to record cerebral activity‚ it also records electrical activities arising from sites other than the brain. These unwanted chunks of electrical activity are termed artifacts and may be divided into physiological and non-physiological artifacts. Physiological artifacts are generated from sources other than the brain (i.e.‚ any other part of the body like the eyes‚ other voluntary and involuntary muscles) and involve head or limb motion and muscular tension.

Nikola Tesla‚ Man of Many Sciences Who is Nikola Tesla? Where would the world be without him today? “Nikola Tesla” by Inez Whitaker Hunt gives us just a glimpse of the contributions that Nikola Tesla made to the modern world. Born into humble beginnings‚ his father an Orthodox Priest and his mother and uneducated woman‚ came a man who would someday contribute some of the most important technology of his time. Some of that technology still in use today. Nikola Tesla was one of the most influential

150 years ago‚ approximately around 1886‚ electricity was becoming a very exciting thing as AC plants started to appear all over the world. This meant great change for not only our establishments but also‚ for families that were near it and could afford it. It was the dawn of aluminum‚ cars and now a better way of life with electricity‚ life was about to get more exciting as well as easier for many families. Around the time of the late 1800’s‚ under the idea of “separate spheres”‚ caring for children
