Question

Conductivity is represented by the symbola)Pb)&#916;c)&#955;d)&#954;Correct answer is option 'D'. Can you explain this answer?

Answer

Units of Electrical Conductivity. Electrical conductivity is denoted by the symbol σ and has SI units of siemens per meter (S/m). In electrical engineering, the Greek letter κ is used. Sometimes the Greek letter γ represents conductivity.

Answer

The symbol of electrical conductivity is kappa(k) and also Sigma or Gamma.

Answer

C

Answer

Conductivity is represented by the symbol σ.

Explanation:
Conductivity is a physical property of a material that describes its ability to conduct electric current. It is represented by the symbol σ (sigma). Conductivity is a measure of how easily electric charges can flow through a material.

Conductivity is an important property in various fields, including physics, chemistry, and engineering. It is used to characterize the electrical behavior of materials and is particularly relevant in the study of conductors and insulators.

Factors affecting conductivity:
- Type of material: Different materials have different conductivity levels. Metals, for example, are generally good conductors of electricity due to the presence of free electrons that can move easily through the material. Non-metals, on the other hand, are usually poor conductors or insulators.
- Temperature: Conductivity can vary with temperature. In general, the conductivity of metals decreases with increasing temperature, while the conductivity of semiconductors and insulators may increase with temperature.
- Impurities: Impurities in a material can affect its conductivity. For example, adding impurities to a semiconductor can enhance its conductivity, a process known as doping.

Importance of conductivity:
- Electrical applications: The conductivity of materials is crucial in electrical applications. Good conductors are used in electrical wiring, transmission lines, and electrical components to ensure efficient and reliable flow of electric current.
- Thermal applications: Conductivity also plays a significant role in thermal applications. Materials with high thermal conductivity are used in heat sinks, radiators, and other cooling systems to efficiently dissipate heat.
- Material characterization: Conductivity is often used as a means to characterize and differentiate materials. It can provide valuable insights into the electrical properties and behavior of a material, aiding in material selection and design considerations.

Conclusion:
Conductivity is a fundamental property that represents the ability of a material to conduct electric current. It is denoted by the symbol σ and is influenced by various factors such as material type, temperature, and impurities. Understanding conductivity is essential in numerous fields and applications where electrical or thermal conduction is involved.
