It is a DC voltage that is applied to the generator's revolving field windings. This produces a magnet field that cuts the generators main coil windings, inducing an electrical current within the main generator windings.

A Traveling wave of excitation is what you know as?
nerve signal
An atom that undergoes excitation and de-excitation emits?
A quanta of light (one photon).
How atomic excitation lead to concept of laser?
How atomic excitation lead to concept of laser?
In synchronous motor theory is excitation current the same as field current?
yes. excitation current is same as field current to my knowledge
What is it called when electrons jump to higher energy level?
excitation
A Traveling wave of excitation is what you know as?
nerve signal
What does coded excitation improve in addition to penetration?
signal to noise ratio
What rhymes with ovation?
Nation, automation, celebration, excitation, deliberation, excitation, penetrationcelebration, excitation, deliberation, excitation, penetration
What is the process of excitation contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.
What are the Applications of excitation transfer theory?
Excitation theory is a misattribution of arousal.
Excitation-transfer theory by zillmann?
Zillman's Excitation Transfer Effect http://doctordigger.blogspot.com/2005/07/zillmans-excitation-transfer-effect.html
Electrical excitation of muscle fiber?
Electrical excitation of a muscle fiber. Skeletal muscle fibers (cells) can be stimulated either by amotor neuron in the body or by a voltage stimulator in the lab. Stimulation given by either method results in a depolarization of the sarcolemma. If the depolarization reaches threshold, an action potential (electrical signal) is initiated.
What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Heart excitation originates in the?
Heart excitation originates in the sino-atrial node.
Which excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
What causes Parametric Excitation in Frequency Resonators?
Google: "Parametric Excitation in Frequency Resonators".
An atom that undergoes excitation and de-excitation emits?
A quanta of light (one photon).
