Megohm measurements reflect classical resistance, while quantized Hall resistance is discrete and quantum-defined, so practical equivalence is complex.
-
This conversion may not be applicable for everyday electrical measurements outside specialized laboratories.
Frequently Asked Questions
-
What does one megohm represent?
-
One megohm equals one million ohms and measures electrical resistance by indicating how strongly a material opposes electric current.
-
Where is quantized Hall resistance used?
-
Quantized Hall resistance is employed in national metrology institutes as a precision standard to realize the ohm and study quantum electrical properties.
-
Can I use this converter for all electrical measurements?
-
This converter is best suited for specialized contexts involving high resistance values and quantum electrical standards, not for general measurements.
Key Terminology
