Who was famous for publishing a formula in 1827 that shows the mathematical relationship between current, resistance and voltage?

Correct option is D

The correct answer is (d) Georg Simon Ohm.
· Georg Simon Ohm (1789-1854) was a German physicist and mathematician best known for formulating Ohm's Law.
· In 1827, Ohm published his seminal work "Die galvanische Kette, mathematisch bearbeitet" (The Galvanic Circuit Investigated Mathematically), in which he described the fundamental relationship between voltage (V), current (I), and resistance (R) in an electrical circuit.
· Ohm's Law is expressed by the formula: V=I×R
· This law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
· Ohm's contributions laid the foundation for electrical circuit theory and paved the way for advancements in electrical engineering.
· Gustav Kirchhoff (1824-1887) was a German physicist known for his work in electrical circuits, spectroscopy, and black-body radiation.
· He formulated Kirchhoff's circuit laws, which describe the conservation of charge and energy in electrical circuits.
