Principle of generator?

Light may be generated in two conditions. a) when a material is heated sufficiently that it glows - so-called black-body radiation, b) when an excited electron; previously raised to a higher energy level than its natural state; is allowed to cool and return to its natural energy level. In this energy shift, it will emit a quantum of light quite specific to the element concerned, and the energy change.


How does a transducer measure current?

a transducer is a device that converts one form of energy to electric energy there are different types of transducers like mic is an acoustic transducer that converts sound energy to electrical energy...resistance changing transducers,inductance changing transducers capacitive type transducer ....change their values in accordance with an analog quantity to b measured like temp etc....this change produces porportional current or voltage which is basically proportional electrical energyTransducer, in electronics, a device that converts electric energy into some other form of energy, or vice versa. Transducers are used in sound systems, in video equipment and in many measuring devices. A transducer used in a measuring device produces an electric current proportional to the strength or intensity of the physical quantity-such as heat, light, or mechanical stress-to which the transducer is subjected. Piezoelectric crystals (crystals that produce an electric current when deformed) and photoelectric cells are transducers; so are loudspeakers, which produce sound from electric energy.


What are the types of transducers?

Sound -> Electrical (microphones)Force -> Electrical (Load Cells)Kinetic -> Electrical (piezoelectric, generators)Light -> Electrical (solar panels)Thermal -> Electrical (thermocouple)Electrical -> Kinetic (Motors)Electrical -> Magnetic (electromagnets)Electrical -> Optical (lightbulbs, LEDs)Electrical -> Thermal (heaters)Electrical -> Audio (speakers)*(see the related link below for more information)A device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa.


What is acoustic signal?

The definition of sound says that it is a disturbance of energy that comes through matter as a wave, but humans perceive sound by the sense of hearing. Our eardrums and the diaphragms of microphones are only moved by the sound pressure motions. Sound pressure is the effect and sound power (energy) is the cause. But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms. Think of sound pressure level meters (SPL meters). So better ask: What is sound pressure? Scroll down to related links and look at "Sound pressure and Sound power - Effect and Cause". Scroll down to related links and look at "Sound - Wikipedia" and "Acoustics - Wikipedia".

Is b-flat chord a part of the electromagnetic energy?

No it is not. It exists in air waves until it hits the ear of the listener. Even if the chord is generated by an electronic instrument, it is a real chord only after sound waves are generated in the air.

How sound energy converts into electrical energy?

according to me an osscilator of a knwn pitch wen connctd to our pitch may hv a possibility to convrt our sound energy in electrical energy as our frequency cn b transsmitted to tat.............. Output when the above is fed into the WA Universal Translator: The sound impinges on either a piezo-electric crystal or a small coil of wire in the field of a permanent magnet. Either of those, when vibrated, creates a small electric current. This technique is used in a microphone.

Which elements can store sound energy?

Sound energy can be stored in elements such as air, water, and solids like metal or wood. These elements can vibrate when sound waves pass through them, storing and transmitting the sound energy in the process.

The total amount of energy in an object is called energy A heat B thermal C temperature D electrical?

The total amount of energy in an object is called energy, regardless of its form (heat, thermal, electrical, etc.).


Where is all of the energy of the sun generated from?

The energy of the sun is generated in its core through nuclear fusion reactions. Hydrogen atoms combine to form helium, releasing large amounts of energy in the process. This energy is then radiated outwards as sunlight.


What is the value of the potential at points a and b?

The value of the potential at points a and b is the measure of electrical potential energy at those specific locations.


What is the minimum range of the transformer in Tesla coil?

Barton B. Anderson states the following: Tesla Coil is a high voltage coil that produces ionic emissions in the form of electrical discharges many times referred to as man-made lightning. This is very different than the lightning generated in an electrical thunderstorm. Different in frequency, power, energy, and obviously how the discharge is generated.
