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.
A rocket is intended to leave the Earth's gravitational ?eld. The fuel in its key engine is a little less than the amount that is essential, and an auxiliary engine, only capa

Five volts are applied across the plates of a parallel plate capacitor. The distance of separation of the plates is .02 meters. What is the magnitude of the electric field i
What is the Interference ? A single frequency light passing through a pair of closely spaced slits will show a pattern of vertical bands, due to alternating constructive and des
CAPACITOR MEASUREMENTS : Many modern digital multimeters incorporate a capacitance measuring facility although this may be limited to just one or two ranges. The diagram below
The coefficient of friction between the load and the flat-bed trailer is 0.40. While traveling at 100km/h, the driver makes an emergency stop and the truck skids to rest in 90m. De
Resistors in dc circuits: Components are said to be in series when they are connected end-to-end providing only one path for the current. Thus the same current passes through
