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 Field We define the electric field as the region or space around a charge within which if we place another charge, then it will experience an electric force on it which can be attractive or repulsive depending on the polarity of the source and the ...

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. Electric Dipole The SI unit of electric dipole moment is coulomb-meter(Cm). The electric dipole moment gives the measure of strength linked with the electric dipole. The middle point of the line joining the two charges +q and –q is called the centre of the dipole. ... Read More

Introduction A charge is a property of matter that causes and experiences electrical and magnetic effects. The basic concept behind charge conservation is that the system's total charge is conserved. It can be defined as: Atoms and molecules make up all of the materials in the world. Normally, all of these atoms and molecules are electrically neutral, with all of their charges balanced. One of the types of charges must be removed in order to electrify a neutral body. A charged body always indicates either an electron deficit or an electron surplus. Electrons are assumed to be negatively charged. By ... Read More
