Basically, Your ground prong is essential to protecting you from being in contact with an "unsuspecting Live current flow."
It eliminates YOU as the primary grounding to whatever your plug is supplying power to, and sends any current flow, manually drawn (like touching it), into the ground prong.
Your feet touching the earth acts as a "grounding" process, but with a ground prong; itself alone acts as the ground for you, allowing you to escape the ability to receive external power.
Black wire to copper screw( hot is marked on outlet) white wire to other side silver screw
(neutral,white is marked on back of outlet) and bare copper wire to green screw.
If the outlet box is metal, attach a 4inch bare copper wire too the copper wire with a ground wire nut (has hole through top of nut) now attach to a green ground screw
on the box and to the green screw on the outlet. This is so both are fully grounded,
and code in most areas.
A two prong plug has no ground, only a hot and neutral.
To act as a ground connection to improve safety in the event of a short circuit.
There are two flat spades and a rounded prong on a three pronged electrical plug. The rounded prong is the ground.
Ground wire
The 3rd round plug is the ground connection.
ground
YES - it will work fine, and hopefully you have grounding in the plug. If you do not, you should also get surge protection and a safety cap when not using. The 3 prong will not create a ground, so it will not change the fact that it is dangerous not to have ground (you know kids and outlets).
No, the wide prong is neutral it is the white wire. The narrow prong is hot it is the black wire. The round prong (in a 3 wire plug) is safety ground it is the green wire.

Is it a plastic prong sealed together
The ground prong is connected to the computer chassis, including the outside of the power supply module. This is a safety feature to ensure that the metal case of the computer and power supply never becomes dangerously electrified in the event of a loose wire. Modifying the power cord not to have a ground prong would violate electrical codes intended to prevent accidental electrocution. That said, the ground prong is not essential for the normal operation of the computer, and the computer will still function without it. Proceed at your own risk.
The 3rd round plug is the ground connection.
ground
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.
YES - it will work fine, and hopefully you have grounding in the plug. If you do not, you should also get surge protection and a safety cap when not using. The 3 prong will not create a ground, so it will not change the fact that it is dangerous not to have ground (you know kids and outlets).
No, the wide prong is neutral it is the white wire. The narrow prong is hot it is the black wire. The round prong (in a 3 wire plug) is safety ground it is the green wire.
No.
On a three prong plug there will be a neutral blade, a "hot" blade and a ground blade. The neutral blade is wider that the "hot" blade. In North America the ground blade is "U" shaped.
Depends on the size of the wire in the extension cord. The 3 prong is just the hot, neutral, and ground.
Change either the plug or the cord. The fourth prong is another ground. It would be easier to change the cord.
