Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.
Thermodynamics is the branch of physics which deals with heat and other forms of energy and also gives relationships between them.
Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.
First posulate of Special theory of relativity is "The laws of physics take the same form in all inertial frames".
Plasticity is the property of the material by virtue of which it does not regain its original shape when applied force is removed.
Most solid materials show elastic behaviour to a lesser or greater extent.
Quantum mechanics is dealing with the behaviour of matter and light on the atomic and subatomic level.
