 How voltage, current, and resistance relate  Chapter 2: OHM'S LAW  Volume I  DC (Site not responding. Last check: 20071006) 
  The first, and perhaps most important, relationship between current, voltage, and resistance is called Ohm's Law, discovered by Georg Simon Ohm and published in his 1827 paper, The Galvanic Circuit Investigated Mathematically. 
  Ohm's principal discovery was that the amount of electric current through a metal conductor in a circuit is directly proportional to the voltage impressed across it, for any given temperature. 
  Ohm's Law is a very simple and useful tool for analyzing electric circuits.
