Question

What do you mean by the dynamic resistance of a conductor?

Answer 1

The dynamic resistance

1. It is the function of potential difference (or current) through the material.
2. It is defined as the ratio of differential change in voltage to a differential change in current.
3. $R=\frac{dV}{dI}$. Here $R$ is dynamic resistance of material, $V$ is potential difference and $I$ is current through it.
4. Dynamic resistance is used to quantify the resistance of non-ohmic materials.
5. The dynamic resistance of a conductor depends on the applied potential difference (Current)
6. It does not follow ohm's law, so it is called a non-ohmic conductor.
