When an electric current flows through a long conductor, each free electron moves?

it would be D ,through a relatively short distance.

in a wire,when an electric field is sent,the valence electrons move at a speed of 30-40 cm per minute.so how does so fast the fan moves as soon as we pull the switch???

well,it is not the electron that moves so fast.it is the electric field that moves at a speed of closely to light speed and it causes every electron of the wire to move.as far as we pull the switch,the electric field is sent to the whole wire and the electrons inside the armeture or core of the fan moves so the fan moves immediately.

What Is Electric Current? | Live Science – Electric current is electric charge in motion. Electrons in a conducting material such as a metal are largely free to move from one atom to another A sufficient electromotive force (emf), or voltage, produces a charge imbalance that can cause electrons to move through a conductor as an electric…Electrons move from the surface of one object to the surface of the other if the second material holds onto its Charges in motion form an electric current. When charge flows between objects in contact, the A conductor allows an electric current to flow through it, but it does not permit the current to…Electric current results when electric charges move – these may be negatively charged electrons Some materials allow current to move better than others. The motion of the free electrons is When an electric current flows through a conductor there are a number of signs which tell that a current…

Electricity | Series And Parallel Circuits | Electric Current – Do electrons flow through the electrolyte? Not necessarily, and now you've also discovered why we The type of flowing charges depends on the type of conductor. To hide all this complexity The reason is that an electron can't move from one side to the other inside the battery without a chemical…Electricity is created when electrons move between atoms. Positive atoms look for free negative electrons and attract them, so that they can be When electrons move through a conductor an electric current is created. A current that always flows in one direction is called a direct current (DC).Electricity is briefly defined as the flow of electric charge, but there's so much behind that simple statement. Where do the charges come from? Where do they move to? How does an electric charge cause mechanical motion or make things light up? So many questions! To begin to explain…

What is Electric Current » Electronics Notes – Electric current is an important quantity in electronic circuits. When a voltage is applied across the conductor or semiconductor, electric On the other hand, if two same or like charges are placed close to each other they get repelled. When a proton is placed closer to an electron, they get attracted.The individual electron moves a short distance. A. Electric fields cause atoms to move in the wire. B. Electrons flow. An alternating current and a direct current flows simultaneously in the same conductor. if the effective value of the alternating current is 5A and the direct current is 10 A, what…Usually no. When the conductor loses electrons from one end it receives electrons from the other end. While it can happen when the conductor is removed from a high voltage circuit Now, you will understand that there can not be loss of electrons from conductor when current passes through it.
