What is the advantage of connecting the outer conductor of a coaxial cable to ground?

To prevent the outer conductor, or shield, from radiating, it is connected to electrical ground, keeping it at a constant potential.

What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
What are the faults in the cable?
Cable faults are normally categorised as (a) conductor-to-earth (ground) faults, (b) conductor-to-conductor faults, and (c) conductor-to-conductor-to earth (ground) faults. In addition to that, we can categorise them by whether they are 'high-resistance' or 'low-resistance' faults.
Can ground conductor use as a neutral conductor in a house wiring?
No. Absolutely not. The ground conductor is not rated to carry constant current flow. It is only rate to carry fault current flow.
What is the difference between a ground conductor and a ground electrode conductor?
# A ground electrode conductor is a conductor that originates at the neutral or equipment ground buses in the main service entrance panel board or separating derived system (e.g. isolation transformer) # A ground electrode is a item that is in contact with the earth (e.g. Building metal frame, underground continuous metallic water pipe etc...) # A ground conductor is a conductor that is used to keep an electrical system continuous. Ground conductors are required, by code, in all PVC conduit runs. Ground conductors are also used to keep all metallic components of the installation at the same zero potential to overcome mechanical connections that would not carry a fault current back to the supply distribution panel.
A conductor directly connected to the Earth?
GROUND
Is ground a good conductor?
of electricity yes
How are the live neutral and ground wires connected to a duplex grounding type receptacle?
The black "hot" conductor goes to the brass coloured screw. The white coloured conductor goes to the silver coloured screw. The bare ground conductor goes to the ground green coloured screw
What does an electric current continually seek a pathway to?
An electrical current continually seeks a pathway to ground.
Is green ground in an extention cord?
Yes, the green conductor is the colour of the ground wire in an extension cord. The black wire is dedicated to be the "hot" and the white conductor is the neutral.
Which wires are positive and negative on coaxial cable?
Most uses for coaxial cable involve transmission of AC/RF signals. The outermost conductor is usually referred to as the "Shield" or "Ground Shield" and is connected to ground potential, while the inner conductor(s) carry the signal(s). The outermost conductor is usually thought of as being at 0 volts, while the AC signal on the inner wire transitions around it in both positive and negative. The terms Positive and Negative have little meaning as regards the AC signals but in some satellite applications, particularly the 18" dish variety, a DC "offset" is applied to the cable to power the Low Noise Block Down Converter (LNB) on the dish, and also varying the amount of the offset between 12 and 18 volts DC to select signal polarization. In this case, the outermost conductor would be negative, and the innermost would be positive regarding the DC offset.
How do you wire a wire to a wire?
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
What is an earth or ground continuity conductor?
An earth or ground conductor that is used for continuity throughout the home is the ground conductor that is found in cable wire sets. What it is used for is to bring everything that it is connected to down to the same potential which is zero. The grounding circuit is a low impedance circuit. If a fault occurs on any equipment and shorts out to ground, this conductor being directly connected to the distribution panel, carries the fault and trips the breaker feeding the faulted circuit.
