Unformatted text preview: Prof. David R. Jackson ECE Dept. Spring 2011 Notes 15 ECE 2317 ECE 2317 Applied Electricity and Magnetism Applied Electricity and Magnetism Potential Integral Formula Potential Integral Formula This is a method for calculating the potential function directly, without having to calculate the electric field first. This is often the easiest way to find the potential function (especially when you don’t already have the electric field calculated). There are no vector calculations involved. The method assumes that the potential is zero at infinity. (If this is not so, you must remember to add a constant to the solution.) Potential Integral Formula (cont.)
