find the approximate current density when an electric field of 5v/m is applied to a copper conductor.the conductivity of copper is 59.6*10^6
To find the approximate current density in a copper conductor when an electric field is applied, you can use Ohm's Law, which states that the current density (J) is equal to the conductivity (σ) multiplied by the electric field strength (E).
The formula to find current density (J) is:
J = σ * E
Given:
Electric field strength (E) = 5 V/m
Conductivity of copper (σ) = 59.6 * 10^6 Siemens/m
To find the current density:
J = (59.6 * 10^6 Siemens/m) * (5 V/m)
J = 298 * 10^6 Siemens * V/m
Therefore, the approximate current density when an electric field of 5 V/m is applied to a copper conductor with a conductivity of 59.6 * 10^6 Siemens/m is 298 * 10^6 Siemens * V/m.
