Introduction Conservation of electric charge is one of the basic laws of nature. During the 18th century, one of the physicists named as Benjamin Franklin discovered the electric charge. He started the study of electricity in 1740 itself. For this discovery he went through some experiments and found the existence of the positive charge and negative charge. But this concept…

Introduction Most people are very doubtful about the terminology ‘Potential’. In our school time when we first time listened to this term, we learned that potential is somewhat related to the position. However, it means capacity or strength. The term electric potential represents the strength of electricity. When we start a study for electricity, the…

Introduction Karl Friedrich Gauss is widely regarded as one of the greatest mathematicians of all time. Some consider him to be the greatest.Gauss discovered a way to think about Coulomb’s law that allows us to calculate the electric field of charge distributions in a straightforward manner. Although Gauss did not discover a new physical law,…

Introduction We know that in the gravitational field an object creates gravitation around it and if any other object is placed inside that region, it will experience a gravitational force. The gravitational field is created due to the masses present but the electric field is created due to charges and the time-varying magnetic fields. Electric…

Introduction A system of two charges +q and -q, equal in magnitude and opposite in polarity segregated by a small distance ‘2a’ is called an electric dipole. The electric dipole moment vector of this system is given as: Images Coming soon Where ‘2a’ is the vector that joins the negative charge to the positive charge.…

Introduction: Charge Distribution Let us take a very light rod AB (as shown in the figure 1) of negligible mass and hang three mass ‘m’ each. So the total mass of the rod will be ‘3m’. But the mass of each part of the rod is not uniform, some parts will have more mass like…

Introduction When we study a charge or a system of charge, we see that every charge has a definite amount of electric field which exerts the electrostatic force of repulsion or attraction on other charges and charged particles according to their nature. The effect of electricity can be experienced with the help of a unit…

Introduction The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions with a charge. The force of attraction or repulsion between the charged particles ends on coulomb’s law. Electricity is…

Introduction Electric charges in the field of electricity and of magnetism, display the fundamental property of particles of matter. Both positive and negative charges exist together within a circuit and therefore display their different characters. For example, when the accumulation of one kind of charge exceeds then it results in positing the character of repealing,…
