Question

Explain the flow of current through a
conductor.​

Answer 1

Step-by-step explanation:

When an electric current flows in a conductor, it flows as a drift of free electrons in the metal. Electricity flows easily through a conductor because the electrons are free to move around in the object. Whenever there is a movement of electrons through a conductor, an electric current is created.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow}{Answer:-}}$

Structurally, a metal can be considered as a regular three dimensional array of atoms/ positive ions at fixed positions and a large number (typically,$\ {10}^{28}$ per cubic metre) of free electrons. Such electrons (sometimes called

conduction electrons) are free to move within the metal. These electrons move at random with average speeds of the order of$\ {10}^{6}$m/s at room temperature.

In the absence of an external electric field, they move with different speeds in different directions and undergo frequent collisions like molecules of an as many electronnles of an ideal gas. On an average, justnby electrons move in one direction as in opposite direction, so that there is no net w of charge. Hence, there is no current in the conductor.

The situation is modified when an electric field is applied across the conductor, using a cell or battery. Then, between successive Collisions, an electron is accelerated and acquires a velocity component opposite to the electric field because of its negative charge. Thus, in addition to random thermal motion, the free electrons move slowly, or drift, in the direction opposite to the electric field constituting an electron current in that direction. The conventional current is taken to be opposite in direction to the electron current
