excitation

English

excitation (countable and uncountable, plural excitations)

The act of exciting or putting in motion; the act of rousing up or awakening.
- 1961 October, “The first 1,250 h.p. Birmingham/Sulzer Type 2 diesels enter service”, in Trains Illustrated, page 607:
  Generator excitation is obtained by a combination of the separately-excited and self-excited fields, and the output is controlled by a resistance in the separate field circuit adjusted by the load regulator under the control of the engine governor.
- 1962 December, “The Oxted Line diesel-electric multiple-units”, in Modern Railways, page 385:
  Wheelslip automatically causes the main generator field excitation to be reduced; the load regulator is forced back to minimum excitation and, if operating in one of the two stages of traction motor field divert, causes reversion to full field.
The act of producing excitement (stimulation); also, the excitement produced.
- 1966, Mike Love, Brian Wilson (lyrics and music), “Good Vibrations”, performed by The Beach Boys:
  I'm pickin' up good vibrations / She's giving me the excitations.
(physiology) The activity produced in an organ, tissue, or part, such as a nerve cell, as a result of stimulation
(physics) A transition of a nucleus, atom or molecule to an excited state by the absorption of a quantum of energy; the opposite of relaxation

the act of producing excitement (stimulation); also, the excitement produced

(physiology) activity produced in an organ, tissue, or part, such as a nerve cell, as a result of stimulation

(physics) change in state as an excited state is formed by the absorption of a quantum of energy
