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 are the advantages of dumb terminal?
Advantages of dumb terminal no one person can misuse his power because his power is given by a main computer which is server.
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.
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 color is not common in receptacle terminal brass silver green black?
black
Is the 1976 ford f250 grounded to the negative battery terminal?
Yes
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.
Should a 3 wire 250 volt drier be grounded?
Yes, most definitely. Provisions for the ground wire in the dryer receptacle should be used. The feeder cable's ground wire is first grounded to the receptacle's junction box ground screw and then taken to the receptacle's ground terminal. The dryer plug configuration will match up to the dryers four wire plug in cable. When the plug is connected into the dryer receptacle the ground terminals of both devices will match and the ground wire will be continuous from the voltage source at the distribution panel and complete the circuit at the dryer. This low impedance electrical path will conduct any ground fault that could occur at the dryer and trip the feeder breaker of the dryer circuit, there by removing the fault current from the dryer circuit.
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 Ending point of a vector?
Vectors are identified by magnitude, or the length of the line, and direction, represented by the arrowhead pointing toward the terminal point. The position vector has an initial point at (0,0) and is identified by its terminal point ⟨a,b⟩.
What color are the terminal of a standard grounding-type receptacle?
green wire is gr gray wire is neutra
Duplex receptacle circuit given 15 amp breaker 225 amp load?
A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.
