Totally Transformers are not real but there planet is real but it is full of dark energy.Anyway if they we're real then you can call the transformers i mean autobot's

What components compose the excitation current of transformer how the are modeled in the transformer's equivalent circuit?
Excitation current Io = Iw + Iu
What is transformer turns ratio excitation current?
This is the current level needed to energize a transformer to its rated voltageThe clue is in the name! 'Excitation' means to create a magnetic field. So the excitation current is the current drawn from the supply which sets up the magnetic field around the core.
What components comprise the excitation current of a transformer?
A transformer's excitation current can be resolved into two components. The first is in phase with the primary voltage, and is responsible for the losses. The second lags the supply voltage by 90 degrees, and is responsible for magnetising the core.
What is exciting current in transformer?
Excitation current is the current necessary to "turn on" the transformer so it can be used. It's energy that is lost in the use of the transformer. Most of this loss I believe is associated with the hysterisis loop, although some will be lost as eddy currents.
A devise that increases or decreases the voltage of alternating current?
TRANSFORMER
What is the significant relationship of the no load loss in excitation current test in transformer?
The no load losses are the losses caused by energizing the transformer. These are constant losses, regardless of loading. This in effect tells you the efficiency of the transformer. (Power in) - (no load losses) = (Power out)
What is knee point voltage of current transformer?
10 % increase in voltage gives you 50 % increase in excitation current is called knee point voltage. To measure this first demagnetise the CT and apply voltage gradually from secondary keeping primary winding open circuited. while doing this above phenomeneo will be obsesrved.
Current travels from a power plant to a transformer that increases voltage through a what?
circuit
A device that increases the voltage of an alternating current is called?
That's called a transformer.
Does a fluorescent ballast use power when no bulbs are in the fixture?
Yes, there is an excitation current that flows through the primary side of the transformer which is located in the magnetic ballast's casing.
In synchronous motor theory is excitation current the same as field current?
yes. excitation current is same as field current to my knowledge
What in a transformer determines whether it increases or reduces current?
The ratio of the primary winding turns to the secondary winding turns. This governs voltage which is directly related to the current and load.AnswerA transformer increases or decreases voltage, notcurrent. The secondary current is determined by the load, and the secondary current determines the primary current. If there is no load, then there is no secondary current, and the primary current is mainly made up of the magnetising current.
