How can you use a circuit to decide whether an object is a conductor or an insulator?
Well, if you have a functioning (=closed) circuit, and introduce an unknown object, then if the circuit is still functioning (=closed) then the object is a conductor. If it stops working, then it's either an insulator or an very poor conductor.
Is a carbon rod a conductor or insulator?
As regards electrical conduction, if the carbon rod is graphite, it's a conductor. If the carbon rod is diamond, it's an insulator. We have to specify the allotrope of carbon used to make the rod to discover whether it's an insulator or conductor.
Is paper envelope a conductor or insulator?
the paper may a certain amount of electricity to flow, depending on the mositure contained within the paper, or whether the paper is wet, or even depending how think the paper is; in which case the voltage charge may travel across the paper.
True Or False Materials that are poor conductors are poor insulators?
No. Something that is a poor conductor must be a good insulator and vice versa. If a material conducts better than it insulates it is considered a good conductor, if it insulates better than conducts it is considered a good insulator. No material can be both a poor conductor AND a poor insulator. It is impossible.
How would you test whether water is a conductor or insulator?
I'm not sure how safe this would be, but here's how I would do it: start with a small lightbulb (Barely larger than the tip of your thumb) a D battery, a plastic cup (A known insulator) and some pieces of insulated copper wire with the tips exposed. Use electrical tape to attach one wire to the posative end of the battery, then to the inside of the empty cup. Attach another wire to the negative end. Touch both wires to the lightbulb, to make sure the circut works. (You may have to mess around with the placement of the wires) If it lights up, then attach another piece of wire to the place on the lightbulb that the positive end was when the light was lit. attach the other end to the cup, on the other side from the one connected to the battery. Then attach the negative wire to the bulb where it worked. Fill up the cup. When it is touching both ends, the light will light up if it is a conductor, and stay dark if it is an insulator. I am going to write the answer next, so if you don't want it, don't read ahead. Water is a conductor.

Is fabric insulator or conductor?
it's an insulator. conductors are things like metals or salts.
Whether plastic foam which contains pockets of air would be a good conductor or a good insulator.?
Because it fills heat slowly
Is electric press a conductor or insulator?
Whether a material is a conductor or an insulator depends on its ability to conduct electric current. An electric conductor is a material that allows the flow of electric charge. In conductors, electrons are loosely bound and can move easily, facilitating the flow of electric current. Common examples of conductors include metals like copper and aluminum. On the other hand, an insulator is a material that does not allow the flow of electric charge. Insulators have tightly bound electrons, and they do not conduct electricity well. Examples of insulators include rubber, glass, and most non-metallic materials. In the context of an electric press, it's important to note that the press itself is typically made of metal, which is a conductor. However, the material being pressed could be either a conductor or an insulator depending on its properties. If the material being pressed is an insulator, it won't conduct electricity well, even though the press itself is a conductor.

Is glass a poor conductor?
It depends on whether you mean heat conductor or electrical conductor; in either case it is a poor conductor at room temperature; but at very high temperature it is a good electrical conductor but still a poor heat conductor
Can you give me a definition of electrical conductive?
'Conductive', in the electrical sense, describes the property of a material which enables an electric current to pass through that material. An electric current is a drift of charge carriers -in the case of a metal, these charge carriers are negatively-charged free electrons, but in other materials, such as electrolytes (conducting fluids) the charge carriers may be charged atoms, called ions. For a material to act as a conductor, it needs to have sufficient charge carriers to support current flow; if there are too few, then we say the material is an insulator. There is no such thing as a 'perfect' conductor or a 'perfect' insulator, but we can list different materials on a scale where one end represents an excellent conductor (or a very poor insulator) and the opposite end represents an excellent insulator (or a very poor conductor). The property used to define whether a particular material is classified as a conductor or an insulator is termed its 'resistivity', expressed in ohm metres.

Which forms of carbon are insulators?
Carbon may be an insulator or it may be a conductor. It depends on which allotrope of carbon we are investigating. Graphite is a conductor, but diamond is an insulator. In either case, the manner in which electrons are bound in the structure determines whether any of them are free to contribute to current flow. In graphite, we find electrons in the conduction band, and it will conduct electric current. In diamond, the electrons are not in the conduction band, and are not available to support current flow.
True Or False Materials that are poor conductors are poor insulators?
No. Something that is a poor conductor must be a good insulator and vice versa. If a material conducts better than it insulates it is considered a good conductor, if it insulates better than conducts it is considered a good insulator. No material can be both a poor conductor AND a poor insulator. It is impossible.
Are gold wire and ice and rubber and yarn and paperclips conductors?
We classify materials into three general categories -- conductors, semi-conductors and insulators. In general, a conductor conducts even below room temperature. A semi-conductor is a poor conductor at room temperature and its conductivity increases with rising temperature. An insulator is a very poor conductor even at rising temperature. A gold wire is made of gold, which is a metal. Metals are mostly conductors. Ice, rubber and yarn don't conduct very well. They are insulators. Note that ice disappears at above-freezing temperature. A paper clip without an insulating coating is a conductor. If it is sheathed with a plastic coating, it is more likely an insulator, depending whether one applies electricity at the exposed ends or not -- the exposed ends can form a conductor. A reliable way to tell whether it is safe to apply a voltage to an item is to check out the arrangement with an ohmmeter. Very loosely defined, a mega-ohm or above is a poor conductor; a giga-ohm is in the insulator territory. A good conductor will read a resistance below a kilo-ohm. I have not discussed sheet resistance or resistivity; it is a more advanced topic.
