Created page with "== Introduction == The Von Klitzing constant, denoted as R<sub>K</sub>, is a physical constant named after the German physicist Klaus von Klitzing, who discovered the quantized Hall effect. The constant is defined as the resistance value between the voltage and current terminals of a Hall effect device when the conductance is quantized. It is a fundamental constant of nature with a value of approximately 25812.807 ohms. Image:Detail-35973.jpg|t..."
