- 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.
- (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
