How does one charge a conductor negatively if you have only a positively charged rod?
1ST. ground the conductor 2nd. move the positive rod CLOSE but NOT TOCUH the conductor u r trying to charge. 3. REMOVE the grouding wire on the conductor
My fuel gauge stoped working after replacing the fuel pump 1993 1.8 IMPREZA FWD?
you crossed wires when putting the fuel pump cover back on. you must of pinched the wires or stripped them so one is grouding. one wire is green one is black. go check
In old automobile we find Positive ground system. Why it was so Why they stopped positive grouding What are pros and cons?
In college we were taught, +ve ground means the wires and electric items in the car are -ve , oxygen is a +ve atom and is attracted to -ve wire etc, causing them to corrode and fail... very expensive repairs replacing wiring etc...., so the battery was turned around to protect the wires and electrics components, but now the panels will rust,..

Explain what an electroscope detects What is grouding and why is it useful?
Eletroscópios são todos os dispositivos que podem ser usados para investigação do desequilíbrio de cargas elétricas em um corpo. O eletroscópio é um dispositivo usado para acusar se algum corpo encontra-se eletricamente carregado. ... Com ele, podemos evidenciar se um corpo está neutro ou eletricamente carregado.
Disadvantage of coaxial lines?
Very vague question, as everything has advantages and disadvantages when compared to similar things. Coaxial lines can only carry a limited amount of data. This is partially why High-Definition cannot stream across a coax-line in-real-time. This seems to be the most pertinent issue of all, so this is all I'm going to say, other than that there are many other issues when compared to competing technologies. Other disadvantages include electrical grouding strategies between dissimilar electrical circuits, ease of installation, and even application (you use coax to wire almost anything, however, doing so requires using special adapters that in some situations requires using adapter, some of which do not exist or need to be specially made). On a last note, Coaxial lines have been superseded by more advanced types of wires.
What is the difference between neutral and ground in a three phase system?
No matter whether we're describing a three-phase service or a a single phase service, the bare copper "earth" or "ground" wire normally carries no current. Its purpose is to provide an emergency path for current if ever there is any accidental contact between a hot wire and the external (or internal) metal parts of any electrical device which a user may be able to touch. The electrical device can be a motor, a water heater, an air conditioner unit or any other kind of appliance.By carrying away the excess current in a fault condition - which should cause the protecting fuse to blow or the circuit breaker to trip - the "ground" or "earth" wire protects the building and its occupants because the power should be cut off before anyone gets electrocuted or any overloaded circuit wiring or appliances catch on fire.The neutral is the normal "return" wire. In systems where the load is supplied from only one hot (or "live") wire, the neutral completes the circuit and carries current back from the load to the power station. In "Y-" or "star-connected" three-phase circuits the neutral doesn't normally carry any current if all three phases are properly balanced.If the three phases actually have unbalanced loads - which can easily happen if each phase is being used to provide power to different single-phase circuits, each with their different loads - then some current will flow in the neutral wire and will result in unbalanced 3-phase currents flowing back to the power station.All the neutral and ground (or "earth") wires in a building are tied or linked together at the incoming service main breaker panel. This is the only place they should ever be tied together because it is "upstream" of all the fuses and/or circuit breakers protecting the hot (or "live") wires for the various circuits installed in the building.Warning: we must never assume that a neutral is safe to touch: it has to be checked with a voltmeter or a voltage indicator to be sure it is not "live". This is because a neutral wire is designed to carry current under normal circumstances.So, if a neutral wire going back to the incoming main breaker panel has not been properly connected - or suffers a deliberate disconnection or some accidental damage which causes it to break - then it and any neutral wires connected to it further downstream will go live up to the break because of being connected to the downstream loads which still have hot feeds coming into them!That is why we should never use a neutral as a substitute for a proper, separate, ground or "earth" wire.If some external accidental damage or electrical breakdown of the wiring's insulation occurred anywhere to the house wiring, to a socket outlet or to an appliance, these things could be very dangerous if there was no such protective wire.For example, if there was no protective ground or earth wire, a fault could happen that is of a kind which did NOT draw enough extra current to blow a fuse or make the main circuit breakers on the incoming supply panel "trip" to cut the current off - but the wiring could still catch on fire and/or someone could be electrocuted!Neutral wires are the return paths to the power generation station for current it supplies to the house or building via single live or "hot" wires in the branch circuits.For more information please click on the Related Questions below.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
