Abstract

Based on conformal mapping，the two methods of solving electric field line equation in two dimensional electrostatic field by the Cauchy-Riemann condition and the complex potential of electrostatic field are given. Further，the electric field lines and equipotential lines are plotted by MATLAB.

Key words： complex electrostatic field; conformal mapping; Cauchy-Riemann condition; complex potential of electrostatic field; electric field line equation; numerical simulation
