🔍 Key Concepts

• Surge (characteristic) impedance of a transmission line depends only on the line’s geometry and the properties of the insulating (dielectric) material • How conductor size and spacing between conductors affect capacitance and inductance per unit length • Role of the dielectric constant of the insulation in determining capacitance and thus impedance

💭 Think About

• Which answer choices talk only about physical geometry and material properties of the line itself, not operating conditions like applied voltage or RF frequency? • Look at ‘dielectric’ and ‘insulating material’—which wording correctly reflects that it’s the material’s property, not a distance, that matters? • Ask yourself: if you turned the power off (zero voltage), would these three factors still exist and still define the surge impedance of that line?

✅ Before You Answer

• Make sure the option you pick does not rely on operating voltage or current; surge impedance is a line property, not an operating condition • Confirm that all three items in the correct choice are independent physical characteristics of the cable construction (geometry + material), not how it’s being used • Check that the dielectric term refers to a material property (dielectric constant), not a spacing or shield description that doesn’t change the material itself

Question 1 of 20

What are the three factors to consider when figuring the surge impedance of a non-resonant transmission line?

Diameter of the conductor, space between conductors, dielectric constant of insulating material

Voltage on RF line, diameter of conductors, space between dielectric

Diameter of shielding, space between dielectric constant, insulating shield around the conductor

None of the above
