• The electric potential at a point in an electric field is defined as being numerically equal to the work done in bringing a unit positive charge … Electric Potential We have been studying the electric field Next topic: the electric potential Note the similarity between the gravitational force and the electric force Gravitation can be described in terms of a gravitational potential and we will show that the electric potential is analogous We will see how the electric potential is related to energy and work We will see how we can calculate the electric potential from the electric field and vice versa Copyright © The McGraw-Hill Companies, Inc. (i) Electric potential due to a point charge The electric eld due to a point charge is E~= kQr^ r2 (10) The electric potential due to a point charge is then, V = Z r 1 kQr^ r02 dl~ = Z r 1 kQr^ r02 dr0^r = kQ Z r 1 dr0 r02 = kQ r (11) (ii) Electric potential inside and outside a uniform shell of charge Take the shell to have radius Rand total charge Q. 2.3 Potential Due To a Point Charge. A second particle of charge is placed on the -axis at . 9. Loading image • • • Similarly, the electric field at point A will be . Furthermore, spherical charge distributions (like on a metal sphere) create external electric fields exactly like a point charge. Point charges, such as electrons, are among the fundamental building blocks of matter. Worked Examples Up: Electric Potential Previous: Electric Potential and Electric Electric Potential of a Point Charge Let us calculate the electric potential generated by a point charge located at the origin. The electric potential due to a point charge is, thus, a case we need to consider. x��[Q�ܶ~��ط�;��(R Point charges, such as electrons, are among the fundamental building blocks of matter.

The topics and sub-topics covered in Electrostatic Potential and Capacitance Class 12 Notes are: 2.1 Introduction. Point objects, Size. Physics 155.3 Electrical Potential due to Multiple Point Charges Because the potential is a scalar, the electrical potential due a set of source charges q i is given by a scalar sum where each r i is the distance from each source charge q i to the field point P q 1 r 1 q 2 q 3 r 2 r 3 P 14, that is a function of only, where is the radial distance from the origin. Electric Potential \(V\) of a Point Charge. kQ V rr r kQ V r Potential is + or – based on sign of the charges Q.Potential is + or – based on sign of the charges Q. The electric potential at a point in an electric field is defined as the amount of work done in moving a unit positive charge from infinity to that point along any path when the electrostatic forces are applied. /Filter /FlateDecode Electric Potential – the electric potential per unit charge between the plates. The Electric Potential Difference The Accelerations of Positive and Negative Charges A positive test charge is released from A and accelerates towards B. Electric Potential Energy for a Pair of Particles (1) To illustrate the concept of the electric potential energy of a system of particles we calculate the electric potential energy of a system of two point charges, q1 and q2 .
