There isn't or shouldn't be any power in coaxial cable. It is just for the TV or computer hook up. Just so you can receive the signal from the broadcaster or internet.
In several ways the previous answer is wrong.
Firstly coaxial cable is exactly like normal 2 wire cable (fig8 cable) except that instead of two separate wires running side by side separated by insulation) one wire is inside the other (again separated by insulation). There are many different types of coax (probably hundreds eg one i use is rg-58 which is for two way radios, another is rg-6 which is used for tv coax)
secondly- if any signal is to be passed through a cable- there has to be power flowing through it- it may be incredibly small (microvolts like from your tv antenna) or very large (hundreds of volts like in a high powered radio transmitter)
Even in a tv coax, if you have a `masthead amplifier' that only has 1 cable running up to the antenna and a funny box behind the tv that has 2 coax leads running into it and a plug-pack from a PowerPoint going into it as well- you would find that you are actually passing power up the coax from the PowerPoint plug-pack to the electronics up on top of the tv mast - power going up and tv signal coming down the same coax at the same time- saves on another two wires having to be run!!!
Many `cable' tv or internet cables have a similar `power over coax' arrangement for powering amplifiers on long cable runs, this is normally stopped by a filter before the end users outlet however (if the filter is faulty this can be the `tingle or zap' that you sometimes get when touching the outer screw connector of the coax plug)

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 is the difference between baseband coaxial cable and broadband coaxial cable?
Iam pretty sure that baseband coax was 50 ohm and was used for networking computer, were broadband coax is 75 ohm and used in the cable tv industry. A baseband signal is the original signal before it is modulated onto a carrier, mulitplexed or mixed. A broadband signal contains many channels which have been modulated or multiplexed onto a common carrier. The significant difference is the bandwidth of each. The impedance of the cable which carries either of them is totally irrelevant to the definition.
What are the disadvantage of coaxial line?
coaxial cable speed is slower than fiber optic cable. it is main disadvantage of coaxial cable
How do you use a splitter to watch cable on two televisions?
You need a TV signal splitter. They're cheap and available just about everywhere, like Walmart, K-Mart, electronics stores. Just split the `antenna out' connection from the cable box. You'll also need a couple more signal wires (coaxial cables) otherwise you'll be two wires short of having what you need. One from the cable box to the splitter and then one for each TV.
What is coaxial Qr?
Coaxial Qr is a coax cable that has been developed to met the demands of broadband or internet. At the moment it is considered to be the best of all the coax cables out there as it is very flexible and reliable.
What cables carry the signal from a cable modem to a PC is it a RCA cable HDMI ethernet or coaxial?
coaxial
How to test a coaxial cable for signal quality?
To test a coaxial cable for signal quality, you can use a cable tester or a multimeter. Connect the tester to both ends of the cable and check for any signal loss or interference. You can also use a signal strength meter to measure the signal strength along the length of the cable.
What is the significance of self-inductance in a coaxial cable and how does it affect the transmission of signals through the cable?
Self-inductance in a coaxial cable is significant because it creates a magnetic field around the cable when current flows through it. This magnetic field can interfere with the transmission of signals by causing signal loss or distortion. To minimize this effect, coaxial cables are designed with specific spacing and materials to reduce self-inductance and improve signal transmission quality.
What is the technical term for a kind of cable that carries a TV signal?
coaxial
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.
How can I test a coaxial cable to ensure it is functioning properly?
To test a coaxial cable for proper functioning, you can use a cable tester or multimeter to check for continuity and signal strength. Connect the cable to the tester and check for any breaks or shorts in the wiring. You can also use a signal generator to send a signal through the cable and check for any interference or loss of signal.
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.

Can a coaxial cable for a TV go bad Can you suddenly lose the signal from an antenna because of a bad cable or connection from the TV to the wall jack Will a new cable solve this problem?
Yes! a coaxial cable can go bad. Yes! you can suddenly lose the signal from an atenna because of a bad cable. A a new coaxial cable may fix the problem as long as the damaged cable is the source of the problem. However if the signal problem is at the tap or one of the splitters in your home you will need to call your cable company to fix the problem.
What is a coaxial cable?
Coaxial cable is an electrical cable with one wire in the center surrounded by a layer of insulation which is then surrounded by an outer braided cylindrical conductor and finally covered with another insulating layer.
