Is steel a conductor or an insulator?

Yes Every metal is a conductor because of the free electrons (Except Silicon and Germanium; They are semi-metals) Yes, steel is a conductor


Can a loose neutral be check at meter?

it depends on where the neutral is lost if its loose on the street side of the meter or grounding electrode conductor one leg will have a higher voltage than the other but the grounding electrode conductor may be large enough to act as the neutral and remove all the phase imbalance this will show current in the ground on the load side everything will look normal if you have 4 identical lights 2 on each leg you will not detect any difference if you turn off one lamp the lamp on that leg will supply the current to the two on the other letting the single lamp see 160 v 50% brighter and the 2 in parallel on the other leg 80v 50% dimmer triplex wire the bare wire is the neutral and the messenger so if a furniture van pulls to the door an snags the cable. the neutral will break leaving about 6' of slack in the hots.( drip loops at the weather head) and they stay connected the grounding electrode conductor is likely connected to the water line and every house on the street is too so the voltage across the break will be less than 1v unless your phase loads are all on on leg which will mean on the order of 1V delta V= i^2*r (#2Al neutral)- i^2*r (#4cu grounding electrode conductor)


How do you tie an unused conductor to ground?

If you are using a single conductor of a multi-conductor cable that is not already identified as the grounding conductor it will first need to be identified as such. The grounding conductor, also known as the equipment ground or ground wire will be identified with green insulation or no insulation at all bare copper/aluminum. At both ends and anywhere accessible shall be marked green every 4" for 1/0 and higher and completely covered for #1 and lower. A service will require one of three bonds: 1. Cold water ground bonded within 5' of where the service enters the premises. 2. Ground rod 1/2" X 8' {standard 125amp service}. 3. Gas Pipe within 5' of entry. If you are referring to a branch circuit bond that originates from an over-current protective device {breaker or fuse} in the distribution/sub-panel the you can bond to cold water pipe or an existing grounding conductor that originates in the same panel and maintains the same size conductor or greater to the panel can be used. A wire to wire bond can be bonded using any wire bonding method used for that size wire {i.e. wire nuts, Buchanan crimps, kernie's, etc....}. For a pipe bond a mechanical screw crimping clamp is a preferred method. It is a two screw clamp that tightens firmly around pipe and has a hole through it with a screw to compress a conductor. It may also have a lug or other means to accomplish wire attachment. The ground rod will have a similar method but smaller diameter clamp to clamp smaller radius material {rod, pipe}. For rod another preferred method will be a "acorn" connector. It's two piece design allows the rod and the wire to pass through it and a screw to compress them together within. There are other methods using thermal chemical known as Cad-Welding but I think if you were in possession of the required equipment needed for this you will already know how to use it and would not be asking on an open forum lol. **Note: When using copper wire brass clamps are used and aluminum wire will need aluminum clamps. *Hint-For Aluminum use a non-oxidizing compound [kno-lox brand is popular] at the point of wire crimp and on the threads of the screw to eliminate oxidation and seizing of the screw for any future adjustments.

Energy is the must for the every cell activities that cell perform in entire physiological process that organism perform. cell require energy for movemants and du=-ivie=sions


Is a paper folder a conductor of electricity?

Not every part of the stapler. Only the metal part is conducting. The top and bottom surfaces of a stapler are normally made of plastic or rubber, which are insulators. ===========================

What does a conductor use to see all parts to be played by the music group?

A conductor reads the "conductor's copy" of the musical score for the piece. That shows all the parts of music required for every instrument included in the piece. If it is a choral work the conductor's copy also shows the musical part - and words to be sung - for every voice in the choir.
