Question

What is the unit of specific conductance in Ohm


Open in App
Solution

The unit of specific conductance is siemen.

Explanation:

  1. Conductivity, also known as specific conductance, is the ability of a material to conduct electricity.
  2. It is the inverse of resistivity, which inhibits the current flow.
  3. The ohm-meter is the unit of resistivity.
  4. So conductivity is measured per ohm-meter or Siemens.
  5. Every substance has a constant conductivity and resistance.
  6. This feature is unaffected by the material's form or size.
  7. The type of material and the temperature are two elements that influence these qualities.
  8. However, resistance and conductance are proportional to the length and area of the material's cross-section.
  9. The distinction between conductance and conductivity is that conductivity does not vary when the length or area of the cross-section is changed, however, conductance does.
  10. The same can be said for resistivity and resistance.
  11. A superconductive is a substance with a resistance of approximately zero.
