George Ohm
electrical resistance was discovered by Georg Ohm in the late 1820's.

while he was trying to discover gravity in 1977
This relationship was discovered by Karl Georg Ohm.

Sir Isaac Newton mentions air resistance in Law Ipublished in his Philosophiae Naturalis Principia Mathematica.
The experiments of Georg Ohm set the foundation for this law, which is also known as Ohm's Law.
Named after Georg Simon Ohm (1789-1854) German physicist who discovered the relationship between voltage, current and resistance in an electrical circuit
Resistance, and therefore resistors, are a part of any electrical conductor. They were not created but rather, discovered and put to use in electrical and electronic circuits.
In the USA, I believe the first recorded case of antibiotic resistance was back in 1947. A little history. Penicillin was discovered around 1928. Human research trials began around 1940-1941. With World War 2, penicillin gained wide social acceptance. Staph was the first organism to develop resistance to penicillin around 1947.

Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
