He was also taught in electrical induction 238 years ago today, the 16th of March 1787 (Calendar 27th of January 1787), the German physicist Ohm was born. The physicist Ohm discovered the correlation between the voltage and the voltage on the surface of the conductor, namely the famous law of Ohm, the physicist Ohm (Georg Simon Ohm, 16 March 1787 ¨C 7 July 1854), the German physicist is in reverse proportion to the electrical induction with its length, and in the case of stable electrical induction; and on 16 March 1787 Ohm was born in Erlangen, Germany. Ohm discovered the correlation between the voltage and voltage on the entire surface of the conductor, namely the famous law of Ohm; he also proved that the
