In the theory of electricity, you must have a current for electrons to all move in one direction.

Is dry soap a conductor of electricity?
This solution is not a good conductor.
Is a metal paper clip a conductor or insulator?
If it is made of metal, it is a conductor.
Is a ruler a conductor of electricity?
Plastic is generally used as an insulator. A plastic ruler would not be a conductor of electricity.
Why is titanium a poor conductor of thermal heat and electricity?
Actually tungsten is a great conductor of heat and electricity. Tungsten is used a light bulb filaments. If Tungsten was a poor conductor of heat and electricity the bulb in the circuit would not glow because there wouldn't be electricity passing through the circuit. Tungsten is also used as an electrode in gas tungsten arc welding. Electricity passes through the tungsten (negative) and moves to the workpiece (positive) for most applications.
Is pure iron conductor of electricity?
Pure iron is the best conductor of electricity in the current world. It transmits up to eight million electrons per minute through a gauge of 10mm. Pure iron can conduct electricity better than copper and can harvest electricity, although it would have to have added allotropes for that to happen.
What are free electrons in a conductor?
They are electrons that are transferred through the conductor thanks to bonds of the atoms within the substance. An example of this kind of bond would be a metallic bond. They're what cause the conductivity
What changes electrical energy into heat?
when electrons flow through a conductor then the material of the conductor offers resistance to excite the electrons in the conductor to release heat energy.
What would be explainable of a good conductor?
It allows the free flow of electrons.
When an electric current flows through a long conductor how does each free electron moves?
The individual electrons will move back and forth, as they do when there is no current. You would have to do very careful statistics to notice that there are slightly more electrons moving in one direction than in the other: the drift velocity (average velocity due to current) of the electrons is typically a fraction of a millimeter per second.
What is the term for a material through which electrons do not readily flow?
This would likely be an "insulator" as opposed to a conductor.
Does the electron oscillates in the conductor or the move from one site to another in the conductor?
When a potential difference exists between two points of a conductor, electrons slowly drift between those two points along that conductor. If there is no potential difference within the metal, then the electrons simply float randomly between atoms within the metal. Electrons would only oscillate in response to an external, oscillating voltage.
What is a light dependent resister?
As light falls on the conductor then emission of electrons would increase the conductivity and so its resistivity decreases. Such a conductor is known as light dependent resistor.
What do you mean by resistivity?
Zero resistance would be a perfect conductor where the electrons move freely without any losses.
Would a copper wire act as the best insulator of electric current?
no it is good conductor because it has free electrons
Is the picture tube a conductor or an insulator Explain your answer?
A picture tube is an insulator. The electrons would gather up and so, create an electric charge when the TV is on. If it was a conductor, the charge would not build up. Hope this helps :)
Which direction do electrons move in when metals react with non metals?
During this type of reaction, the electrons would move from the metal to the non-metal. The transfer of electrons allows both material to maintain a full outer valence.
Why do electrons flow through a wire?
An electrical current is simply the flow of free electrons in and on the conductors. So they are a bit like water molecules in a garden hose. And like those water molecules the flow of free electrons can be physically impeded by whatever is in or on the electrical conductor. When a material is a good conductor, the atoms and molecules of that good conductor do not get in the way of the free electrons. They do not resist the flow of those electrons very much. So even with just a low voltage to push the electrons along, the flow, the current of the electrons is high. But when a material is a bod conductor, the atoms and molecules of that bad conductor do physically get in the way of those free electrons so that they cannot flow freely through the conductor. The resistance is high in a poor conductor. So it takes a relatively higher voltage to push electrons along in a bad conductor...if indeed they can be pushed at all. Some materials are so bad at conducting it's almost impossible to move those electrons along.
