Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:
ادامه مطلبThe superposition principle is the idea that a system is in all possible states at the same time, until it is measured. After measurement it then falls to one of the basis states that form the superposition, thus destroying the original configuration. The superposition principle explains the "quantum dness" observed with many experiments.
ادامه مطلبWorking Principle of Solar Cell. When light reaches the p-n junction, the light photons can easily enter in the junction, through very thin p-type layer. The light energy, in the form of photons, supplies sufficient energy to the junction to create a number of electron-hole pairs. The incident light breaks the thermal equilibrium condition of ...
ادامه مطلبMill contends that justice is a feeling based in an individual's animal instinct for self-preservation, and this instinct applies to entire communities through humankind's sympathetic nature. As such, Mill argues that justice is analogous to the utility principle, as it is ultimately concerned with the happiness and good of society as a whole.

ادامه مطلبA solar cell is basically a junction diode, although its construction it is little bit different from conventional p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.
ادامه مطلبThe Working Principle of Hammer Mills (Step-by-step Guide) A hammer mill is an essential machine in the pharmaceutical and food processing industries. You can use it to crush, pulverize, shred, grind and reduce material to suitable sizes. Even though there are many types of hammer mills, the working principle is still the same.

The protection of liberty is central to liberal theories about the nature and function of law. Following John Stuart Mill, liberals argue against the enforcement of morality on the ground that society's view of what is morally right does not justify the use of compulsion or control.
ادامه مطلبThe operating principle is simple: the fluid, carrying the suspended particles, enters the cyclone tangentially, spirals downward and produces a centrifugal field in free vortex flow. Larger particles move through the fluid to the outside of the cyclone in a spiral motion, and exit through the spigot with a fraction of the liquid.
