exclusion principle physics

No two atoms can have the same quantum state. Hence, all electrons have discrete energy states. If there are 'n' orbits, then there are 2n possible energy levels which are splitting and creating a band of energy (electrons possessing a range of energy level..

The generator is an application of electromagnetic induction. It works on the principle that when a wire is moved in a magnetic field, then the current is induced in the coil. A rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horse shoe type magnet...

AC Dynamo is based on the phenomenon of electromagnetic induction. That is, when the relative orientation between the coil and the magnetic field changes, the flux linked with the coil changes and this induces a current in the coil. As the armature coil rotates, the angle Q changes continuousl..

The underlying fact on which the principle is based was discovered by Archimedes in about 300 B.C. The story goes that the King of Sicily suspected that the goldsmith has mixed some silver in his crown and cheated him. Without destroying the crown he wanted to know the truth. Archimedes ..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equ..

Archimedes' Principle - An iron needle sinks in water but a huge ship floats on the surface of water. All objects whether inside the liquid (or fluid) or partially inside, appear to be lighter than in air. This is because liquids (or fluids) exert upward force on the immersed object. This..
