A rod of pure silicon (resistivity = 2300 *m) is carrying a current. The electric field varies

A rod of pure silicon (resistivity = 2300 Ω*m) is carrying a current. The electric field varies sinusoidally with time according to E = E ₀ sin ωt where E ₀ = 0.410 V/m, ω = 2πf, f = 120 Hz.

Part A:

Find the magnitude of the maximum conduction current density in the wire.

jc= (A/m ² )

Part B:

Assuming ∈ = ∈ ₀ , find the maximum displacement current density in the wire, and compare with the result of part A.

jD= (A/m ²⁾

Part C:

At what frequency f would the maximum conduction and displacement densities become equal if ∈ = ∈ ₀ (which is not actually the case)?

f = (Hz)

Part D:

At the frequency determined in part C, what is the relative phase of the conduction and displacement currents? Δφ= (degrees)
