| | Georg Simon Ohm: The Discovery of Ohm's Law |
 | | Georg Ohm, German mathematician and physicist, began his important publications in 1825. |
 | | Ohm's law, named after its discoverer, states that the potential difference V between the ends of a conductor or resistor R and the current I flowing through R are proportional at a given temperature: |
 | | Ohm's law is never completely accurate, if R is assumed to be constant, for "real world" devices, because no real device is an ohmic device for every voltage and current - at some level, the device will open or short, for example, by burning up or arcing. |
