Electric Field Lines
Michael Faraday (1791 - 1867) introduced the idea of lines of forces. They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at each point is in the di..
General Properties of Electric Lines of Force or Field Lines
The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert..
Electric Field
The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that poin..
Case I - Uniform Field
The figure shows field lines passing through a rectangular surface of area A perpendicular to the field lines. The electric flux passing through this surface is given by the product of electric intensity and the surface area perpendicular ..

The above figure shows the electric field of a positive point charge. The electric field is directed away from the charge and potential is positive at any finite distance from the charge. If we move away from the charge, i.e., in the direction of..

Consider a system of charges q 1 , q 2 , ..q n placed at distances r 1 , r 2 , ..r n with respect to some origin. Then the electric field intensity due to all these charges at a point is found out using the intensity due to the number of charges q 1 , q 2 , ..q n . Then the give..

Electric field produced by a dipole is known as dipole field. Let +q and -q be equal and opposite point charges separated by a small distance 2l. The strength of an electric dipole is measured by a vector quantity known as electric dipole moment kn..

Electric Charge - The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated by simple experiment..
Electric Charges and Field Conclusion
Conclusion - Principle of electrostatics and electromagnetism play a very vital role in all modern scientific developments. Coulomb's law may be regarded as merely a special case of Gauss' law or we can say Gauss's law is generated form of Coulomb's law. Gauss' law makes it possible to calculate in..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
The tutor let me do the work and corrected me when i made a mistake. They didn't just show me how to do it. They gave me instructions. We managed to do several problems.I really like this service - cindy
