, /Length 3774 The magnitude of electric field at P due to the point charge is given by . 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 . A second particle of charge is placed on the -axis at . + Q. 14, that is a function of only, where is the radial distance from the origin. 3.3 Electric Potential due to Point Charges Next, let’s compute the potential difference between two points A and B due to a charge +Q.

V for voltage (the symbol and unit are the same) V = PE. (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. potential at a given point is the electric potential energy of a small test charge divided by the charge itself SI Unit of Electric Potential joule/coulomb volt (V) 7 2). 2.5 Potential Due To a System of Charges Suppose we have to calculate electric potential at point due to a single point charge situated at , where . %PDF-1.4 What is electric charge? The electric potential due to a point charge is, thus, a case we need to consider. Bringing another charge will face attractive or repulsive force from the first charge and the work done to bring it from infinity to the point is stored in the form of potential energy. 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. electric /qIt is impossible to find the V at any point in an electric field.

Loading image • • • Similarly, the electric field at point A will be . b. ΔU = qV. The electric potential due to a point charge is, thus, a case we need to consider. See our Privacy Policy and User Agreement for details. 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. 2. We have to calculate the potential for each pair.
