What is a coaxial cable?
Q: What is a coaxial cable?
A: A coaxial cable is a special electrical cable used to transmit signals.
Q: What is the purpose of the insulation on a coaxial cable?
A: The insulation on a coaxial cable is used to make it stiff and to prevent the electromagnetic field carrying the signal from interfering with or being interfered with by external electromagnetic fields.
Q: What are some common uses for coaxial cables?
A: Coaxial cables are commonly used for Cable TV and can also be used for computer networks, although this became rare in the 21st century.
Q: How are coaxial cables constructed?
A: Coaxial cables are typically made of a conducting wire with insulation, another layer of conducting material, and a mantle.
Q: What is the function of the conducting wire and conducting material in a coaxial cable?
A: The conducting wire and material are used to transmit a high-frequency or broadband signal.
Q: How does the EM field carrying the signal exist in relation to the inner and outer conductors of a coaxial cable?
A: The electromagnetic field carrying the signal exists ideally only in the space between the inner and outer conductors.
Q: Are there different types of coaxial cables?
A: Yes, there are different types of coaxial cables that satisfy different standards.
