This conversion is not typically applicable outside controlled experimental or standardization settings.
Frequently Asked Questions
-
What does one ohm represent in electrical resistance?
-
One ohm is the electrical resistance between two points of a conductor when a potential difference of one volt produces a current of one ampere.
-
Where is quantized Hall resistance commonly used?
-
It is used mainly in national metrology institutes for resistance standardization and in quantum physics research laboratories.
-
Can I use quantized Hall resistance in everyday electrical measurements?
-
No, quantized Hall resistance appears only under specific experimental conditions and is not suitable for general practical measurements.
