Who is the mathematical equation E=I/R named after?

Thomas Edison
George Ohm
Aldo Rossi
Nikola Tesla

The correct answer is: George Ohm

The equation E=I/R is named after Georg Simon Ohm, a German physicist and mathematician. This equation represents Ohm’s Law, which defines the relationship between voltage (E), current (I), and resistance (R) in an electrical circuit. According to Ohm's Law, the voltage across a conductor is directly proportional to the current flowing through it and inversely proportional to the resistance of the conductor. This foundational principle is essential in electrical engineering and is widely used to analyze electrical circuits. Understanding Ohm's contributions is vital for anyone working with electrical systems, including those in recreational vehicles.
