What is the standard unit of measure for conductivity?

• A. Mho
• B. Siemens
• C. Ohm
• D. Volt

Answer: (B)

The standard unit of measure for conductivity is Siemens. Conductivity is a measure of a material's ability to conduct an electric current, and the Siemens unit is specifically defined as the reciprocal of resistance measured in ohms. This relationship is important in electrical engineering and cathodic protection, as it allows for the assessment of how well a material, such as soil or water, can facilitate the flow of electric current. Mho is an older term that was historically used to refer to the same concept, as it is also the reciprocal of ohm. However, Siemens has become the preferred unit in modern applications. Ohm, on the other hand, measures resistance rather than conductivity, and volt measures electric potential. Therefore, Siemens accurately reflects the standard unit of measurement for conductivity in electrical contexts.
