George Simon Ohm

George Simon Ohm (1787-1854)

Georg Simon Ohm was a German physicist born in Erlangen, Bavaria, on March 16, 1787. As a high school teacher, Ohm started his research with the recently invented electrochemical cell, invented by Italian Count Alessandro Volta. Using equipment of his own creation, Ohm determined that the current that flows through a wire is proportional to its cross sectional area and inversely proportional to its length or Ohm’s law.
George Simon Ohm adalah seorang fisikawan jerman yang lahir di Erlangen, Bavaria pada tanggal 16-maret-1787. Dia hanyalah seorang guru SMA yang memulai risetnya saat teknik Electrochemical Cell ditemukan oleh Alessandro Volta dari Italia.
Using the results of his experiments, Georg Simon Ohm was able to define the fundamental relationship between voltage, current, and resistance. These fundamental relationships are of such great importance, that they represent the true beginning of electrical circuit analysis.
Dari hasil eksperimennya George Simon Ohm menemukan hubungan dasar antara Tegangan, Arus dan Resistansi. Hubungan dasar ini menjadi sangat penting dan menjadi cikal bakal semua acuan untuk menganalisa sirkuit listrik sampai masa kini.
Unfortunately, when Ohm published his finding in 1827, his ideas were dismissed by his colleagues. Ohm was forced to resign from his high-school teaching position and he lived in poverty and shame until he accepted a position at Nüremberg in 1833 and although this gave him the title of professor, it was still not the university post for which he had strived all his life.
Sayangnya, pada saat dia mengumumkan penemuan itu di tahun 1827, ide itu dicekal oleh para koleganya. Dengan tidak mengenal putus asa dan rasa malu George tetap mengajar di kelasnya dan hidup dalam tekanan ekonomi sampai akhirnya idenya diterima di Nuremberg pada tahun 1833 hingga mendapat gelar profesor. Yang patut diteladani walau gelarnya tinggi ia tetap bersahaja tidak sok ilmuwan dan terus berjuang sepanjang hayatnya.

Ohm the Genius! the Mozart of Electricity …
