Analogies between Gauss’s law and Ampere’s law:
- Gauss’s law says the electric flux through a closed surface is proportional to the charge within the surface.Ampere’s law says the line integral of B.ds around a close path is proportional to the current that passes through that path.
- In Gauss’s law,the imaginary and arbitrary closed surface is taken enclosing a charge.In ampere’s law ,an imaginary and arbitrary closed curve enclosing current is taken.
- Both laws use the concept of flux the flow of field lines through a surface to determine the field strength.
- They also both relate the integral of the field over a closed geometrical figure to a fundamental constant multiplied by the source of the appropriate field.
