The current density in a conductor is `5 A //m^2` when an electric field of 50 V/m is applied across it. Calculate the conductivity of the material.

Explanation

To calculate the conductivity of the material, we can use the relationship between current density (J), electric field (E), and conductivity (σ). The formula is given by:

\[ J = \sigma E \]

Where:
- \( J \) is the current density in A/m²,
- \( \sigma \) is the conductivity in S/m (Siemens per meter),
- \( E \) is the electric field in V/m.
