🔍 Key Concepts

• Velocity factor definition in transmission lines • Role of dielectric material between conductors • Difference between physical length of a line and electrical length

💭 Think About

• Which physical part of a transmission line actually determines how fast an electromagnetic wave travels along it? • Does changing the load or termination at the end of the line change the wave speed in the cable, or just reflections and standing waves? • What property in the cable design makes the signal travel at some fraction of the speed of light in vacuum?

✅ Before You Answer

• Remember that velocity factor is a ratio compared to the speed of light in vacuum • Check which option relates to the insulating medium between conductors rather than to the ends of the line • Verify that the factor is not primarily set by length or resistivity, but by wave propagation in the line structure
