How Electric Conductance Works
What is Electric Conductance?
Electric conductance measures how easily electric current flows through a material. It is the opposite of resistance. When resistance is high, conductance is low. When resistance is low, conductance is high.
Conductance is measured in siemens (S). One siemen equals one ampere per volt. This unit helps us understand how well materials conduct electricity.
Basic Formula
G = 1/R
Where G = Conductance, R = Resistance
This simple formula shows that conductance and resistance are opposites. If you know one value, you can easily find the other by dividing 1 by that value.

Frequently Asked Questions
What is electric conductance?
Electric conductance measures how easily electric current flows through a material. It is the opposite of resistance. Materials with high conductance allow current to flow easily, while materials with low conductance resist current flow.
How do I convert siemens to microsiemens?
To convert siemens to microsiemens, multiply by 1,000,000. For example: 0.001 S = 1,000 μS. This conversion is useful when working with small conductance values in electronics and water testing.
What is the difference between conductance and resistance?
Conductance and resistance are opposites. Conductance (G) = 1/Resistance (R). When resistance is high, conductance is low. When resistance is low, conductance is high. Both measure electrical properties but from opposite perspectives.
Why is conductance important in water testing?
Water conductance shows how many dissolved minerals and salts are in water. Pure water has very low conductance. As minerals dissolve in water, conductance increases. This helps test water quality and purity levels.
What units are used for conductance?
The main unit is siemens (S). Smaller units include millisiemens (mS) and microsiemens (μS). The old unit "mho" (ohm spelled backwards) is sometimes still used and equals one siemen.
How do I calculate conductance from resistance?
Use the formula G = 1/R. If you have a 10-ohm resistor, the conductance is 1/10 = 0.1 siemens. If you have a 100-ohm resistor, the conductance is 1/100 = 0.01 siemens. Lower resistance means higher conductance.
