Why must the outer conductor be separated from the inner one when using coaxial cable?

No signals can pass along a coaxial cable if the outer conductor is not kept electrically separate from the inner one.
Along the entire length of the cable the inner conduuctor and outer shield must never be connected together anywhere because, if they get joined together, the signals will be shorted-out.

Which of the following influence the bandwidth of a coaxial cable?
The length of the cable, the gauge of the inner conductor, the material used as dieletric.
What cable types has a inner-core wire conductor and wire-mesh outer conductor 1 utp 2 stp 3 coaxial 4 16g-4?
Coaxial.
What are the uses of coax cable in the world of technology?
Coaxial cable, or coax, is an electrical cable with an inner conductor surrounded by a flexible, tubular insulating layer, surrounded by a tubular conducting shield. The term coaxial comes from the inner conductor and the outer shield sharing the same geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880.[1]
What is the Speed of Coaxial Cable?
The speed of the coaxial cable is usually between 10 and 100 Mbps. The coaxial cable consists of a hollow outer cylindrical conductor that surrounds a single inner wire that is made of two conducting elements.
What are the characteristics of coaxial cable?
Coaxial cables are conductors that send an electrical signal through an inner conductor which is surrounded by a protective insulating layer and sealed by a shield. The cable itself is protected by the outside insulating layer. Coaxial cable is commonly used for video and CATV transmission. The advantage is that electromagnetic fields have less leakage outside the shield.

What does 'coaxial cable' mean?
The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency.
What is the purpose of a coaxial cable?
The purpose of a coaxial cable is to act as a transmission line for a radio frequency signal. The electromagnetic field carrying that signal exists only in space between its inner and outer conductors.
Why inductance of a coaxial cable is expected to increase when the radius of the outer conductor is increased?
Because there is more room in the cable for the magnetic field to form. The magnetic flux density is set by the current in the cable, and with a bigger space that flux density produces more actual flux. The inductance is the flux divided by the current, so a wider cable has more inductance. But if the inner conductor is also increased in size by the same ratio, the effect is negated and the inductance is the same as before.
What cable type usually includes a solid plastic core?
Coaxial cables usually include a solid plastic core. The core is made of solid insulation material that helps to maintain the shape and structure of the cable, while also providing insulation for the inner conductor. This type of cable is commonly used for television and internet connections.
