## Electrostatic Potential and Capacitance Class 12 Notes Chapter 2

Point charges, such as electrons, are among the fundamental building blocks of matter. Furthermore, spherical charge distributions such as charge on a metal sphere create external electric fields exactly like a point charge. The electric potential due to a point charge is, thus, a case we need to consider. We can use calculus to find the work needed to move a test charge q from a large distance away to a distance of r from a point charge q. To find the voltage due to a combination of point charges, you add the individual voltages as numbers. To find the total electric field, you must add the individual fields as vectors, taking magnitude and direction into account. What is the voltage 5.

## HC Verma Class 12 Physics Part-2 Solutions for Chapter 29 - Electric Field and Potential

In physics , Gauss's law , also known as Gauss's flux theorem , is a law relating the distribution of electric charge to the resulting electric field. In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of how that charge is distributed. Even though the law alone is insufficient to determine the electric field across a surface enclosing any charge distribution, this may be possible in cases where symmetry mandates uniformity of the field. Where no such symmetry exists, Gauss's law can be used in its differential form, which states that the divergence of the electric field is proportional to the local density of charge. The law was first [1] formulated by Joseph-Louis Lagrange in , [2] followed by Carl Friedrich Gauss in , [3] both in the context of the attraction of ellipsoids. It is one of Maxwell's four equations , which form the basis of classical electrodynamics.

This article is about the quick summary of electrostatics for class 12 and iitjee. Electric charge can be defined as is the intrinsic characteristic that is associated with fundamental particles due to which they produce and experience electrical and magnetic effects. Charges are of two types.

Point charges, such as electrons, are among the fundamental building blocks of matter. Furthermore, spherical charge distributions like on a metal sphere create external electric fields exactly like a point charge. The electric potential due to a point charge is, thus, a case we need to consider. The potential at infinity is chosen to be zero. To find the voltage due to a combination of point charges, you add the individual voltages as numbers.

Electric field is defined as the electric force per unit charge. An electric motor - is an electrical machine by which electrical energy is converted into mechanical energy, for driving various mechanisms. The Coulomb constant can also be written in terms of the permittivity of free space. The surface charge density of a thin charged disc of radius R is s. Leave a Reply Cancel reply. Mcq Electrical.

PDF Recent experiments demonstrated that the essential electrospinning mechanism is a rapidly whipping dielectric liquid jet in an electric field. Positive 2. If a proton is moved against the coulomb force of an electric field — a Work is done by the electric field b Energy is used from some outside source c The strength of the field is decreased d The energy of the system is decreased

Electric potential , the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Typically, the reference point is Earth , although any point beyond the influence of the electric field charge can be used. The diagram shows the forces acting on a positive charge q located between two plates, A and B, of an electric field E. The potential energy for a positive charge increases when it moves against an electric field and decreases when it moves with the electric field; the opposite is true for a negative charge. Unless the unit charge crosses a changing magnetic field , its potential at any given point does not depend on the path taken. Although the concept of electric potential is useful in understanding electrical phenomena, only differences in potential energy are measurable. If an electric field is defined as the force per unit charge, then by analogy an electric potential can be thought of as the potential energy per unit charge.
