ENERGY LEVELS
The energy levels, measured in electron volts (e.v.) in which orbiting electrons exist comply with a law of physics which states that energy can be given to electrons only in discrete amounts (quanta) which means that there are energy values that an electron cannot acquire. From this it can be deducted that there is a forbidden energy gap between each of the allowed energy bands K to O.
The width of the forbidden energy gap between the top of the valence band and the bottom of the conduction band determine the electrical conducting properties of materials.
Illustrates the Electric Motors? An electric motor is basically the reverse of an electric generator. It is a machine which turns electrical energy - AC from the wall or dire
Energy Transformation for a Dart In that case of the dart being launched from the spring gun and the just forces doing work upon the dart are internal forces. Initially, the da
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
A long solenoid is fabricated by closely winding a wire of radius 0.5 mm over a cylindrical nonmagnetic frame so that the successive turns nearly touch every other. What would be t

Equilibrium can be spited in given types: (i) Stable equilibrium : After showing a charged particle from it's equilibrium point, if it goes back then it is called in stable equ
What is Centrifugal Force? Centrifugal force is the force that is equivalent in magnitude but opposite in direction to the centripetal force, which is the force directed toward
Clock spring balance A sensitive balance for use among 0-1 g or 1-10 g is readily made using a piece of clock spring and a block of wood or cotton reel. Fasten the wooden b
Which of the subsequent would be a good choice of a Gaussian surface to use to find an expression for the electric field? Because of an infinite line of positive charge with a unif
