Question
Define the term conductivity of a conductor. On what factors does it depend?
✓
Answer
Conductivity of a conductor is the current flowing per unit area per unit electric field applied.
Alternate Answer
conductivity $\sigma = \frac{j}{\text{E}}$
Depends upon number density i.e. nature of material, and relaxation time i.e. temperature.
