What is Specific Conductance?
Specific Conductance (SC) is a measure of how well water can conduct an electrical current.
What is resistance?
Is the opposition to the passage of an electric current.
Conductance = ?
1 / resistance.
What is conductance?
The degree to which an object conducts electricity, calculated as the ratio of the current that flows to the potential difference present.
What is conductivity?
The degree to which a specified material conducts electricity
What is resistivity?
An intrinsic property that quantifies how strongly a given material opposes the flow of electric current.
