Help with Equipotential Curves

Remember, before you plot an equipotential curve, you must load the package for it:


  <<Graphics`ContourPlot3D`

Assuming your potential is u(x,y) and it has been previously defined, here is how you would graph the equipotential curves
u=0, u=.25, u=.32, u=.5, u=.75

(Do not evaluate the next cell, it is a text cell!)

equipot=ContourPlot[Evaluate[u[x,y]],{x,0,5},{y,0,5}, ContourShading->False,
ContourStyle->Dashing[{.02}],Contours->{0,.25,.32,.5,.75},AspectRatio->Automatic];
