In which year did Georg Simon Ohm formulate the equation I = V/R which shows the relationship between voltage, current and resistance?
1828
The correct answer is 1828.
Key aspects of Ohm's contributions include: Defining the concept of electrical resistance. Establishing the direct proportionality between voltage and current and the inverse proportionality between current and resistance. Providing a consistent mathematical framework for analyzing simple electrical circuits. The unit of electrical resistance, the ohm (\Omega), is named in his honor to recognize his significant contributions to the field of electricity.
