What is the resistance of a conductor ? State the factors on which resistance of a conductor depends? How is it related to conductivity of the conductor? View Solution How does the resistance of a conductor depend on: (a) length of the conductor?
The resistance of a conductor depends onthe cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is...

Cryogenic high-purity aluminum conductors offer greatly reduced resistive energy losses and conductor mass for high energy pulsed power systems. These benefits result from high RRR (residual resistivity ratio) or low electrical resistivity of these conductors. Previous experiments have shown significant ...
What is the resistance of the copper wire? Take the resistivity of copper to bIn an electrical circuit, the current passing through a conductor varies inversely with the resistance. Suppose that when the current is 8A (amperes), the resistance is 15 ohms. What is...
Which of the following statements are true? Check all that apply. (A) The resistance of a conductor is proportional to the resistivity of the material of which the conductor is composed. (B) Semicon Explore our homework questions and answers library ...
The specific penetration depth of the electromagnetic signals (the skin depth) depends on a combination of the bulk resistivity and the signal frequency. The MT exploration technique is particularly sensitive to the presence of interconnected high-conductivity (i.e., low resistivity) material phases,...
In special cases, the ground resistance should be no more than 5 ohms (no more than 10 ohms in an area with high soil resistivity). The current probe and voltage probe of the ground resistance tester must be vertical to a power line or an underground metal pipe. Use a ground resistance...
of a material is the inverse of the resistivity. Conductivity is usually denoted by the Greek letter σ. The SI unit of conductivity is siemens per meter. It must be noted that conductivity is specifically a property of the material at a given temperature. The conductivity is also known as ...
To solve the question regarding the relationship between resistivity and conductivity as the temperature of a conductor increases, we can follow these steps:1. Understand the Definitions: - Resistivity (ρ):
