Frequently Asked Questions
-
What is the ESU of resistance?
-
The ESU of resistance is the electrical resistance unit in the CGS electrostatic system, often called the statohm, used in theoretical electrodynamics with Gaussian units.
-
Why convert from ESU of resistance to EMU of resistance?
-
Conversion enables translating resistance values between two CGS subsystems—electrostatic and electromagnetic—allowing consistent interpretation of theoretical and historical data.
-
What is the conversion factor between ESU and EMU of resistance?
-
One ESU of resistance equals 8.987552 × 10^20 EMU of resistance, reflecting a very large difference between these units.
-
Are these units used in modern electrical measurements?
-
No, both units are largely obsolete and mainly appear in specialized research, theoretical contexts, or historical archives.
