![]() ![]() ![]() The area around a charge where its effect can be felt is called an electric field. The SI unit of electric flux is $\mathrm$$ Conclusion However, a precise definition of the current is required. The concepts we have seen so far will help to form a qualitative idea about the power flow. As the electric field strength of a point electron decreases with increasing distance from the electric charge, its electric flux also decreases with increasing distance. The area of both A and B is equal, the number of electric field lines crossing the rectangle in area B is greater than the number of electric field lines crossing the rectangle in area B. Let us consider two small rectangular-shaped surfaces perpendicular to the field in regions A and B. The electric field of a point electron is shown in the figure. Figure 1 can be used to easily understand what is electric flux. It can take a positive or negative value. The number of electric field lines obtained in the specified surface when electric field lines flow through that surface is called Electric flux. ![]() Lines of charge are straight or curved lines drawn in the direction in which a uniform electric charge tends to move in an electric field. Hence, the lines representing the electric field are called lines of force. The direction of the electric field is known as the direction of force acting on a small positive charge placed in the field. Because this force works without the charges touching each other. This force belongs to the type of non-contact force. The force between electric charges is called electric force. An atom consists of elementary electric charges. Rutherford who carried out their research in the late 19th and early 20th centuries. The atom was known to be electrically neutral through the pioneering studies of scientists such as J.J. ![]()
