Note : when the lines are red - the applet is calculating the electric field .. wait a second for it to finish.
Introduction : This applet illustrates the Electric field for a line segment of positive charge. We can increase the length of the line segment (basically, we are approximating the charged line segment by a series of discrete charges, close together .. the more charges, the longer the line). As we approach an infinite length, we will get the electric field pattern from an infinite charged wire.
Note : The simulation starts with just one charge - the smaller the finite line segment is (or the further away you are), the more it approaches the Electric field of a point charge.
