Does electricity move through a conductor or an insulator?
The answer is a little more complex than a neat, pat answer. Electric flow may be seen as forward propagation of electrons, or backwards propagation of positive "holes" which may move through or around a medium, or as the movement of ions through a medium. Depending on the dielectric strength of an insulator, and the voltage/amperage of the charge in question, the electricity may move through, over, or around an insulator.In some cases, an electric current can move easily through both an insulator and a conductor, but in most cases, electricity moves easiest through a conductor. Conductors are usually metals or metalloids that have are joined together through metallic bonding. Metallic bonding results in positive metal ions floating in a sea of electrons. The "delocalized nature" of the electrons (electrons spread out) allows charge to flow easily through a conductor.
How electricity generated in dyanamo?
A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.
Is electric charge moving in uniform motion produce both electric and manetic field?
Electric charge produces an electric field by just sitting there. It doesn't have to move. If it moves, it produces a magnetic field. It doesn't matter how the motion would be described.
What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
Is metal a good insulator?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.Source: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/conins.html
When an electric current moves through a long conductor each electron moves?
The free electrons moves through a relatively short distance.
What electric charge crates a magnetic field?
Moving charges produce magnetic fields.Answer 2In other words, when the charge moves along a conductor it creates an electric current. The current induces a magnetic field around the conductor.
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
What exactly is current?
Current is the flow of electric charge in a circuit. It is measured in amperes (A) and represents the rate at which electric charge moves through a conductor, such as a wire. Current is essential for transferring energy and powering electrical devices.
When an electric current flows through a long-conductor each free electron moves?
The free electrons moves through a relatively short distance.
What happens when there is a build up of an electric charge on an object?
The charge repels so if it's a conductor the charge moves as far away as possible (the side of the object). It will also attract other objects with an opposite charge, or repel ones with like charge.
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
What cause the pointer to move in a galvanometer?
Basically, the pointer moves due to measuring the direct current (flow of electric charge) through an electric circuit.

How do kinetic flashlights work?
A bar magnet moves back and forth through a coil. Moving a conductor through a magnetic field (or vice versa) generates a flow of electrons. The electrons are used to charge a capacitor, and the saved charge can be released gradually to power the flashlight bulb.
Why does test charge moves with zero acceleration to any point in the electric field?
They don't. If there is an electric field, any electric charge will be subject to a force, and therefore to an acceleration. Only in the special case that the charges are on the surface of a good conductor, they won't move because the charges quickly move to a state of equilibrium. In other words, once such a balance is reached, they won't move around any more.
How does electricity cause magnetism?
Changing the amount of magnetic field (known as "flux") through a conductor exerts a force on charged particles (electrons in the wire). A change in magnetic field strength in a region of space induces an electric field which circles the magnetic field lines, surprisingly whether or not there is a conductor there or not. It turns out that magnetism and electricity are inherently linked, they are kind of manifestations of the same thing. If "something" has the property of electric charge, it creates an electric field. If that something moves, it creates a magnetic field.
