DESCRIPTION:This seminar is part of the lunchtime seminar series for the 
 Centre for the History of Science\, Technology and Medicine (CHSTM). Lun
 chtime seminars are typically no more than 30 minutes in length\, follow
 ed by a period for audience questions (ending before 2pm). All are welco
 me.\n\nUntangling Ohm's apparatus\n\nCharlotte Connelly (University of C
 ambridge)\n\nAbstract:\n\nIn the early nineteenth century a series of su
 rprising revelations changed how natural philosophers understood electri
 city. Fierce debates raged between adherents to a chemical theory of the
  battery\, and followers of Volta who saw the contact between two differ
 ent metals as the source of electrical power. Meanwhile Ørsted's discove
 ry of electromagnetic effects inspired theories of electrical fields and
  led to the discovery of thermoelectricity. In the midst of these debate
 s the mathematically talented Georg Simon Ohm found himself teaching at 
 a progressive college in Cologne\, equipped with an unusually well stock
 ed 'Cabinet' of scientific apparatus. This paper will describe the key f
 eatures of Ohm's torsion balance\, exploring the theoretical background 
 that underpinned the different component parts of the apparatus. The dev
 elopment of the balance drew on the theories of the day\, and its design
  betrays Ohm's own theoretical leanings. The now famous law that Ohm pro
 duced using his torsion balance was first published in 1826\, but failed
  to gain recognition in Germany for well over a decade. By positioning O
 hm's work in the midst of the wide ranging debates about theory and meth
 odology in electrical science\, this paper aims to offer some reasons fo
 r the slow uptake of Ohm's law
