The correct Answer is:C To solve the question regarding the effect of temperature on the resistivity of a conductor, we can follow these steps: 1. Understanding Resistivity: - Resistivity (ρ) is a property of materials that quantifies how strongly they resist the flow of electric current....
The a.c. conductivity of a liquid crystalline organic conductor is measured for the first time within the mesophase. The charge transfer complex is still conducting above the transition temperature of 120[ddot]C; but each stay in the mesophase produces an irreversible degradation of the transport...

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note
Resistivity Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity ...
