When two objects are touching each other there is no net change in there?
True if they are conductors, false if they're (or one of them) is an insulator.
Are gases conductors?
No. Gases are not good conductors of electricity nor heat (compared to other states of matter.)
Prevents surfaces in contact from sliding past each other?
Sliding friction prevents surfaces in contact from sliding past each other.
Metals and other materials that transfer heat and electricity easily are called?
Conductors

Can the sand harm your copper pipes?
I have found that anything under ground can go bad after a while. But the worst thing for under ground pipes is for it ( copper ) to be touching each other and touching cement or rocks
What are the ways of decreasing friction?
You can stand on bare ground tile or any other conductors (water, aluminum, etc.)
What does buffer do?
A buffer prevents two things from touching or meeting, such as the buffer between two people keeps them from meeting and potentially harming each other.
Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
What will happen to someone who is holding a live wire in the air and not touching the ground?
Nothing will happen , as the current always flows from higher potential to lower potential and if the person is touching only live wire then, there is no other path for the current to flow , but if the person touches the ground , the ground is at "0" potential, so, the current tries to flow from live wire to the ground via person , so the person gets shock in that case but not when a person is only touching the live wire and not the ground.
Can you run 220V on two conductors plus ground?
Yes, 1 conductor is live, the other neutral (just like a normal plug)
Why are both conductors and insulators are both required to construct the electrical wiring in homes?
The conductor is metal, usually copper today, but some applications use aluminum. The conductors "conduct" the current. The insulation protects the wire from damage and keeps you from getting shocked and keeps the conductors from touching each other and thereby causing a short circuit.
Your drivers side seatbelt cable came out of the top.?
Check the wires that you cut, they may be touching each other or shorting to ground.
What is the purpose of a tone generator and tone probe?
They are used to trace wiring. There may be multiple conductors in a bundle that are unmarked, or perhaps unmarked wires that go to different locations. The tone generator is connected to a pair of conductors (or one conductor and ground), and the probe is used to find the same conductor on the opposite end. The probe is used to look for the conductor that is carrying the tone. In a bundle of conductors, or several conductors in a raceway, the tone may be induced, or "bleed" into other conductors. In this case, the desired wire has the strongest tone. Connecting the generator to one conductor and ground tends to induce the signal into other conductors. Toning a pair, with neither one grounded, is the most selective, making identification more sure.
What color is the line wire in an electrical system?
The only designated colors in electrical wiring in North America are White as a neutral and Green as a ground wire. All other colors can be used as live wires. There are specific colors designated by the electrical code for phase wiring.Answer for European SystemsThe relevant regulations define all conductors, other than the protective (earth/ground) conductor, as 'live' conductors. In Europe, the line conductor has a nominal potential of 230 V with respect to the neutral conductor.In Europe, the the three line conductors of a three-phase system are identified with brown, black, and grey insulation, respectively. For single-phase systems, brown is normally used. Neutral conductors are identified using blue insulation, and protective (earth/ground) conductors are identified using green/yellow stripedinsulation.
What are ungrounded conductors and grounded conductors?
Ungrounded conductors, also known as "hot conductors," carry current from the source of power to the load. They are not connected to the ground and usually have a voltage potential. On the other hand, grounded conductors are connected to the ground or neutral point of the power system and are typically used to complete the circuit path and provide a return path for current. They usually have a voltage potential close to zero.
