• Consider the two point charges as shown in the Fig. 3.3.1 The flux lines originating from positive charge and terminating at negative charge are shown in the form of tubes.
Properties of Flux Lines
Subject and UNIT: Electromagnetic Theory: Unit I: (c) Gauss Law and Applications
Key Point : Thus the total number of lines of force in any particular electric field is called the electric flux. It is represented by the symbol ψ Similar to the charge, unit of electric flux is also coulomb C.

• Uptill now the forces and electric fields due to only point charges are considered. In addition to the point charges, there is possibility of continuous charge distributions along a line, on a surface or in a volume. Thus there are four types of charge distributions which are, 1. Point charge 2. Line charge 3. Surface charge 4. Volume charge
