Seems like a great place to trot out one of my favorite bits of electronic lore. The inverse of resistance (1/R) is called conductance and its unit is the Mho

The inverse of resistance (1/R) is called conductance and its unit is the Mho (No really!) When you calculate the resistance of resistors in parallel you're converting the Ohms to Mhos, adding them together, then converting back to Ohms.

Oh, it seems I'm a little dated: "electrical conductance is measured in siemens (S) (formerly called "mho"s and then represented by ℧)." Oh well.

- exmadscientist 5y agoI don't know why they had to get rid of the mho. It's a fun unit! And far less easy to confuse with the second (s) than the siemens (S). Many, many, many people write "mS" when they mean "ms". Normally this isn't indicative of a major character flaw or anything, but when you're in an interview, describe yourself repeatedly as "detail-oriented", and also make that mistake repeatedly... your "detail-oriented" interviewers will notice.
- stavros 5y agoOh man, is this one of those units that makes way more sense almost everywhere, like 2π for the diameter instead of the radius? Am I going to start noticing that "this equation would have been much easier using the conductance" now?
