What year did George Simon Ohm define the laws among voltage, resistance, and current?

• A. 1816
• B. 1826
• C. 1836
• D. 1846

Answer: (B)

George Simon Ohm is credited with formulating the relationship between voltage, current, and resistance, which is known as Ohm's Law. He published his findings in 1827, and this foundational work in electrical engineering laid the groundwork for understanding how electrical circuits operate. The law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor.

The year 1826 was significant because it marks the time when Ohm's principles were initially introduced and began to gain recognition in the field of electricity. This pivotal year established a fundamental concept that still applies to electrical engineering today. The other years presented in the options do not correspond to the correct period when Ohm's Law was introduced, making 1826 the accurate choice.
