What is meant excitation?
noun. the act or process of exciting or state of being excited. a means of exciting or cause of excitement. the current in a field coil of a generator, motor, etc, or the magnetizing current in a transformer. (as modifier)an excitation current.
What is meant by excitation of electron?
Electron excitation is the transfer of a bound electron to a more energetic, but still bound state. This can be done by photoexcitation (PE), where the electron absorbs a photon and gains all its energy or by electrical excitation (EE), where the electron receives energy from another, energetic electron.
What is ionization and excitation?
The key difference between excitation and ionization potential is that excitation potential is the energy required to jump from one energy level to other while ionization potential is the energy required to remove an electron from an atom.
What is excitation in engineering?
Definition of ‘excitation’ a. the current in a field coil of a generator, motor, etc, or the magnetizing current in a transformer. b.
What is excitation in radiography?
Excitation is one means by which ionizing radiations dissipate their energy in matter. It is an indirect method of inducing chemical change through disruption of atomic bonds.
What is excitation wavelength?
Excitation spectra. A fluorophore is excited most efficiently by light of a particular wavelength. This wavelength is the excitation maximum for the fluorophore. This wavelength is the emission maximum for that fluorophore. The excited fluorophore can also emit light at wavelengths near the emission maximum, as shown.
What is excitation in synchronous motor?
The word Excitation means the production of flux by passing current in the field winding. The arrangement or the system used for the excitation of the synchronous machine is known as Excitation System. To excite the field winding of the rotor of the synchronous machine, direct current is required.
What is meant by excitation?
ex·ci·ta·tion | \\ˌek-ˌsī-ˈtā-shən, ˌek-sə-\\. : excitement especially : the disturbed or altered condition resulting from stimulation of an individual, organ, tissue, or cell.
What does excitation function mean?
Excitation function is a term used in nuclear physics to describe a graphical plot of the yield of a radionuclide or reaction channel as a function of the bombarding projectile energy or the calculated excitation energy of the compound nucleus. The excitation function typically resembles a Gaussian bell curve.
What is the electrical term excitation mean?
The process of generating a magnetic field by means of an electric current is called excitation. Field coils yield the most flexible form of magnetic flux regulation and de-regulation, but at the expense of a flow of electric current.
What is meant by excitation of generator?
Excitation in generators Amplifier principle. Except for permanent magnet generators, a generator produces output voltage proportional to the magnetic field, which is proportional to the excitation current; if there is no excitation current Separate excitation. Self excitation. Brushless excitation.
