What is electric field line representation?
In this post, we use electric field lines representation to model qualitatively the direction and strength of electric fields produced by simple point charges, pairs of charges, dipoles and parallel charged plates as a part of the Prelim Physics course under the module Electricity and Magnetism and sub-part Electrostatics.
The following two videos cover electric field line representation in various examples.
Part 1: Crash Course electric field
Part 2: Examples of electric field lines
