Conserved current

In physics a conserved current is a current, , that satisfies the continuity equation . The continuity equation represents a conservation law, hence the name. Indeed, integrating the continuity equation over a volume , large enough to have no net currents through its surface, leads to the conservation law where is the conserved quantity. In gauge theories the gauge fields couple to conserved currents. For example, the electromagnetic field couples to the conserved electric current. (Wikipedia).

8 AWESOME EXAMPLES Conservation of angular momentum!!!

In this video you can see eight different examples Conservation of angular momentum. Also i explain that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

When is a Physical Quantity Conserved in Quantum Mechanics?

It is always interesting to know whether there are quantities in a physical system that are constant over time, so-called conserved quantities. In this video, we will explore the condition for whether a quantity is conserved and what this has to do with the Hamiltonian of the system. Ref
