Exercise: The conduction current flowing through a wire of cross section A with conductivity $\sigma = 2 \times 10^7 S/m$ and relative permittivity $\epsilon_r = 1$ is given by $I_c = 2 \sin \omega t$ (mA). If $\omega = 10^2 rad/s$, find the displacement current.

Step 1
85 x 10^-12 F/m), A is the cross-sectional area of the wire, and dE/dt is the rate of change of electric field. In this case, the relative permittivity (ε) is given as 1, which means the electric field is not affected by the material. Show more…
