Frequently Asked Questions
-
What is ESU of resistance?
-
ESU of resistance is an electrical resistance unit in the CGS electrostatic system, related to the potential difference and current in electrostatic units and often found in Gaussian unit literature.
-
What does one megohm represent?
-
One megohm equals one million ohms and measures how strongly a material opposes electric current.
-
Why convert from ESU of resistance to megohm?
-
Converting allows translating theoretical or historical resistance values into SI units used in modern practical measurements and applications.
