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.
Capacitor-start-capacitor-run single-phase motor : In this case, two capacitors are used one for preliminary and other for running purpose as shown. The capacitor used for prelimin
Using principles of special theory of relativity derive mass energy relation, illustrate it with an example. A beam of particle of half life 2.0 x 10-8 sec. travels in a laborat
Diamagnetism is a basic property of all matter, though it is generally very weak. It is due to the no cooperative behaviour of oepenrbiting electrons when exposed to an applied mag
The points where amplitude is minimized are called as nodes.
