The transmission of high frequencies in a coaxial cable is determined by
Show Hint
High-frequency transmission in coaxial cables is influenced by the dielectric properties and skin effect.
Updated On: Jan 6, 2026
- \( \frac{1}{\sqrt{LC}} \) where L and C are inductance and capacitance
- \( (LC)^2 \)
- the impedance L alone
- the dielectric and skin effect
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Coaxial Cable Transmission.
The transmission of high frequencies in coaxial cables is influenced by both the dielectric properties of the materials and the skin effect, which causes higher frequencies to propagate along the surface of the conductor.
Step 2: Conclusion.
Therefore, the correct answer is option (D).
Final Answer: \[ \boxed{\text{(D) the dielectric and skin effect}} \]
