Conductance (also known as electrical conductance) is defined as the potential for a substance to conduct electricity. It is the reciprocal of resistance and is measured in Siemens (S).
The calculator uses the formula:
Where:
Explanation: The formula calculates the electrical conductance by dividing the specific conductance by the cell constant of the electrolytic conductor.
Details: Accurate conductance calculation is crucial for determining the electrical conductivity of solutions, which is important in various fields including electrochemistry, water quality testing, and material science.
Tips: Enter specific conductance in S/m and cell constant in m⁻¹. Both values must be positive numbers greater than zero.
Q1: What is specific conductance?
A: Specific conductance is the ability of a substance to conduct electricity, measured in Siemens per meter (S/m). It is the reciprocal of specific resistance.
Q2: What is cell constant?
A: The cell constant in an electrolytic conductor is the ratio of the distance between the electrodes to the cross-sectional area of the electrodes, measured in m⁻¹.
Q3: What are typical values for specific conductance?
A: Specific conductance values vary widely depending on the material. For example, copper has a high specific conductance (~5.96×10⁷ S/m), while distilled water has very low specific conductance (~5.5×10⁻⁶ S/m).
Q4: How does temperature affect conductance?
A: Conductance generally increases with temperature for most materials, as higher temperatures provide more energy for charge carriers to move.
Q5: What are the applications of conductance measurements?
A: Conductance measurements are used in water quality monitoring, battery testing, corrosion studies, and determining the concentration of ions in solutions.
