Gig-Ohm resistor
I have never heard the term Gigaohms used with resistors. Is this a
valid term? With computer hard drives, if a drive is 1000 megabytes, it's called one gigabyte. Using some resistor color code software I have, it does not use that term. For example, brown black gray says 1000M. or red red white is listed as 22,000M In real life I have never used any resistor with that high of a capacity, I dont even know if they are made, but would 1G or 22G be valid for the examples above? |

Gig-Ohm resistor
Yep have used G ohm resistors and have measured currents in the 1E-12 region.
For that matter I replaced a 10 megohm 200 Watt resistor. It was a bleed resistor on a 15 kV supply, |
