I believe you are asking for a description of the electrical "Earth" or "Ground" symbol (?) It is drawn as 3 horizontal lines (one above another), of decreasing length toward the top. The bottom line is intersected at its centre by a short vertical line that heads downward. The symbol is usually drawn inside a circle. An "Earth" or "Ground" wire is normally identified by Yellow and Green striped sheath or tape.

What happen if high voltage supply directly grounded?
If the voltage is so high of the order of 20,000 to 30,000 volts or higher (which is high enough to ionize air between the power terminal and the nearest negative terminal/ground, chances are that you'll get a spark even before you touch the ground. However, once the terminal is grounded, current just flows down through to the ground and all you end up with is wastage of power...it does nothing. However, whether it sparks the way it does with a lightning bolt (a step leader followed by several return strokes that all apear as one single spark because it happens so quickly) or whether you end up with streaks of light as in st.elmo's fire will depend on the shape of your power terminal. Spherical surfaces have a lower surface charge density as compared to pointed surfaces so you're likely to get a plasma like formation with a pointed power terminal. In any case, once grounded, the current just flows down to the ground and that's the end of it - power wasted!
Why does the computer restart every time you touch the outside of the case?
It's probably not grounded properly. Make sure the outlet is grounded and that they house wiring is properly grounded.
What is the purpose of Terminal Services Manager?
Terminal Services Manager is a component of Windows Server. It allows users to view information about sessions, users, and processes for all terminal servers in a trusted domain. Additionally, it allows various management tasks to be performed on terminal servers.
What is an opening of the computer connected to a card or to place on the motherboard called?
Perhaps a port (opening), or a bay (contained receptacle)?
What is the difference between leftmost and rightmost derivation in the context of parsing algorithms?
In parsing algorithms, the difference between leftmost and rightmost derivation lies in the order in which non-terminal symbols are replaced with terminal or non-terminal symbols. In a leftmost derivation, the leftmost non-terminal symbol is always replaced first, while in a rightmost derivation, the rightmost non-terminal symbol is replaced first. This affects the structure and order of the resulting parse tree.
What is a duplex grounded receptacle?
A duplex receptacle has two devices in a composite assembly on one yoke. It is the receptacle that is what you commonly think of as a receptacle [two places to plug in a lamp...] rather than a single receptacle, which has a place to connect one device. Removing the connecting bar as described in earlier answer merely allows two circuits or separate control of the two devices. original answer: a duplex receptacle is a normal looking receptacle but the little piece of copper bar between the terminal screws on the power side has been broken off and two different circuits feed the two screws- WRONG!
Which terminal of battery is grounded in vehicles and why?
Negative terminal is grounded to the vehicle. Because the system is a negative ground system. Electricity will not flow unless it has a path to ground.
How can I wire a switched outlet using a wiring diagram with power supplied to the receptacle?
To wire a switched outlet with power supplied to the receptacle, follow the wiring diagram provided. Connect the hot wire from the power source to the brass terminal of the receptacle. Connect the neutral wire to the silver terminal. Then, connect the hot wire from the switch to the brass terminal on the other side of the receptacle. Finally, connect the ground wire to the green terminal. Make sure to turn off the power before starting and consult a professional if needed.
Where is the positive and negative terminal of the overhead wire for local trains?
One terminal is the overhead wire, and the other terminal is the track, which is grounded.
Why is one terminal of a three-phase AC generator grounded?
only neutral point is gronded not a terminal ,
What is the purpose of a receptacle pigtail in electrical wiring?
A receptacle pigtail in electrical wiring is used to connect multiple wires together and then connect them to a single terminal on a receptacle. This helps to ensure a secure and reliable electrical connection, as well as to prevent overloading the receptacle.
Is the 1976 ford f250 grounded to the negative battery terminal?
Yes
What color is not common in receptacle terminal brass silver green black?
The color green is not commonly used for receptacle terminal screws. Brass and silver are typical colors for the screws, while black is often used for the insulating coating of the screw.
Can you connect a 220 volt stove to a 120 volt circuit?
Yes, this is a safe connection. A range is usually wire rated at 40 amps and the manufactures do not make a 40 amp rated receptacle. The code requires the next highest rated receptacle be used which is a 50 amp rating. This is why the range receptacle is rated at 50 amps. This receptacle is known as a 3 pole 4 wire grounding receptacle, 14-50R 125/250 volt. Black wire to terminal X, red wire to terminal Y, white wire to terminal W and ground wire to terminal G.
How can I safely install a split-wired receptacle in my home?
To safely install a split-wired receptacle in your home, you should first turn off the power to the circuit you will be working on. Then, remove the existing receptacle and separate the tab connecting the two hot terminals. Connect the hot wires to each terminal, ensuring they are securely attached. Connect the neutral wires to the neutral terminal and ground wires to the ground terminal. Finally, carefully insert the receptacle back into the electrical box, secure it in place, and turn the power back on to test the installation.
Is there a power consumption difference when a receptacle or switch is back stabbed verses the wire being around the screw terminal?
No, it is just two different ways to connect the wires to the receptacle. Most electricians use the screw terminal because it makes a more secure connection.
What is the proper installation procedure for a 50 amp 4 wire receptacle?
To properly install a 50 amp 4 wire receptacle, first turn off the power to the circuit. Connect the black and red wires to the brass terminals, the white wire to the silver terminal, and the green or bare wire to the green terminal. Secure the wires with the appropriate screws and cover the receptacle with a faceplate. Test the receptacle to ensure it is working correctly before use.
