Whose law explains the relationship between electric current, voltage and resistance?
TechnologyPhysics
Quick Answer
Georg Ohm’s law states that current equals voltage divided by resistance. It is written as I = V/R.
The Full Story
Georg Ohm formulated what is now called Ohm’s law in the 1820s, and he published it in 1827. The law describes how current, voltage and resistance are related in many electrical circuits. It is fundamental in electronics, engineering and physics. Ohm’s contribution is honored in the unit of resistance, the ohm.
Key Facts
1.Published in 1827
