Areas of Contribution in Physics:

• Electricity and Magnetism

Contributions to Physics:

• Ohm's Law: V = I R or Potential Difference = Current * Resistance
• This is true so long as temperature of the resistor remains constant

History/Fun Facts:

• Started out as a high school teacher
• Ohm's Law was considered invalid when it was first published
• Became a professor
• Made his own wire which was consistently good quality
• Spent a good number of years living in poverty
• Was the director of the Polytechnic Institute
• Passed away at the age of 65
