Frequently Asked Questions
-
What does reciprocal siemens measure?
-
Reciprocal siemens (1/S) measure electrical resistance, equivalent to ohms, representing a device's opposition to electric current.
-
When should I use megohms for resistance?
-
Megohms are used to measure very high resistance values, especially in insulation testing and high-impedance instrumentation.
-
Why are megohm values very small when converted from reciprocal siemens?
-
Because megohms represent large resistance units, converting smaller resistance values from reciprocal siemens results in very small decimal numbers.
Key Terminology
-
Reciprocal Siemens [1/S]
-
