noun
- a unit of electrical resistance equal to one millionth of an ohm
Usage: technical; electrical engineering
Examples
- The circuit’s resistance was measured at 50 microhms.
- Precision instruments can detect resistance changes as small as a few microhms.
- The wire’s resistance increased by several microhms when heated.
- Engineers use microhm measurements for high-precision electrical work.
- The contact resistance was only 2.3 microhms.
- Microhm readings help identify faulty connections in sensitive equipment.
