Only a very tiny fraction of an inch before scattering off another electron or atom. This scattering distance is independent of wire length.
An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. Its so simple, though my friend from extraminds help me with proper answer.
Even though silver is the best conductor of electricity, it is extremely expensive. Thus silver is not used to make electical wires. Silver is also very soft to be used as electric wires.
It is a safety measure for devices that have a metal case where a failure in the device could cause the case to be connected to the hot side of the circuit. By grounding the case the breaker will trip instead of you getting a shock.
eddy current loss in the transformer core is reduced by
To reduce skin effect.CommentHollow conductors are not used on electricity transmission lines. Transmission-line conductors are normally manufactured of stranded aluminium conductors, wound around a steel-wire core. The steel core improves the conductor's tensile strength.Hollow conductors are, though, used as 'wave guides' in radio-frequency circuits. However, their purpose is not to reduce skin effect (in which most of the current flows close to the surface of the conductor), but to save copper -if most of the current flows close to the surface, then there's little point in using solid copper!AnswerHollow conductors are used on very high voltage underground cables, which are cooled by passing oil or gas through the conductors.
A conductor can have a wire through which an electric current enters or leaves. This conductor allows the flow of electricity between two points, providing a pathway for electrons to move through.
A poor conductor, like iron or steel.
it doesnot depend on meta l or non metal it depends on valence electron ........
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.
Both
True. When a magnet is moved near a conductor, such as a wire, it causes a change in the magnetic field around the conductor. This change induces an electric current to flow in the conductor, resulting in the formation of electricity.
it is the rate at which electric charges pass though a conductor. The charged particle can be either positive or negative. In order for a charge to flow, it needs a push (a force) and it is supplied by voltage, or potential difference. The charge flows from high potential energy to low potential energy.
it is electron because there are free electrons in a conductor .The atoms are fixed on their places.The positive ion (as a result of emission of an electron which is negatively charged ) remains still on its place and hence the free electrons are responsible for the current flow . In solutions and gases the positive ions can also move because they are free to move unlike in the metal
True electric currents refer to the movement of electric charge carriers through a conductor, such as electrons in a wire. It is this flow of charge that powers electrical devices and circuits. The direction of the current is defined as the flow of positive charge, even though in reality it is often negative charges (electrons) that are moving.
The prevailing theory is that the atoms in the conductor share electrons, and they seem to move around at random in the conductor material. When a voltage is applied across the conductor, the electrons tend to move in that direction, but they are still pretty random. This average trend is what we measure as current.
Electrical current doesn't work quite the way that you would think. A simple way to describe electrical current is to imagine a straw filled with marbles. Each marble represents an electron. If you push an electron in one end of the straw, and the straw was full, a marble would exit the other end of the straw. However, while that example gives an idea of what is going on, electricity is actually exactly the opposite of that. An electron is "pulled" out of one end of a conductor, which crates an electron "hole". An electron next to the hole moves into that empty spot, and so on and so on. So, even though you could visualize the electricity moving through the conductor as "pushing a marble", it's really "pulling one out" and marbles are moving to "fill the gap". (This is known as hole movement in electricity). Different metals have different levels of conductivity. The conductivity refers to how easily electrons can move through the metal. The less conductivity, the more "resistance" there is. When electrons are forced through a metal that has a high resistance, heat is generated. This is why the burner on your electric stove gets hot; a lot of electricity is being pushed through a metal that has a high resistance, and therefore gets hot. The electric flow through Metal by the move of Electrons from one place in that Metal to another place.
Not simultaneously. Though it can alternate. If you mean in one circuit there can be alternative directions in which the current can move. Electrical currents go from the negative to the positive since electron (electricity is a lot of electrons) is negative so is directed to the positive.
