Answer: d
Explanation: Dissipation factor refers to the tangent of loss angle. It is the ratio of conduction current density to displacement current density. When both are same, the loss tangent or the dissipation factor will be unity.

Explanation:
The dissipation factor is defined as the ratio of the power loss in a dielectric material to the reactive power stored in the material. It is given by the equation:
Dissipation factor (D) = tan δ = Ploss/Pr
where δ is the phase angle between the voltage and current in the dielectric material, Ploss is the power loss in the material, and Pr is the reactive power stored in the material.
When the conduction current density and displacement current density are the same, the phase angle δ is zero, which means that the voltage and current are in phase. This occurs when the frequency of the applied voltage is low.
At zero phase angle, the dissipation factor is unity, which means that the power loss in the material is equal to the reactive power stored in the material. This occurs because the voltage and current are in phase, and the power is dissipated in the form of heat due to the resistance of the material.
Therefore, when the conduction current density and displacement current density are the same, the dissipation factor will be unity.
