Question

How to measure the conductance?

Answer 1

Conductance

1. The conductance of a material is a measure of the ability of that material to carry a current.
2. The transfer of electricity through the conductor results from the movement of charged particles.

Measurement of conductance

1. Conductivity is the measure of conductance. ,
2. The conductivity of a material determines the ability to pass a conduction current under the influence of the electric field.
3. Conductivity,$\sigma =\frac{J}{E}$, where E is the applied electric field and J is the conduction current density.
4. Another form of conductivity is $\sigma =\frac{l}{AR}$ or $\sigma \propto \frac{1}{R}$, where R is the current resistivity, A and l are the cross-sectional area and length of the body. Low resistance materials have a greater current conductivity.
