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.
What are "Overtones" and "Harmonics" ? How are they build in an open pipe? Derive the mathematical equations for the frequencies of the harmonics produced in an open pipe.
The record for the highest speed achieved in laboratory for a uniformly rotating object was 2.01*10^3 m/s for a0.15-m long carbon rod. What was the period of rotation of the rod?
These resistors are usually of carbon composition, carbon film on a ceramic rod and sealed in evacuated glass tube. End connections are made up of copper clad nickel-iron alloy.
They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current. Voltage is the electromotiv
