Eddy current loss depends primarily on the material's electrical conductivity, the frequency of the alternating current, and the thickness of the conductive material. Higher conductivity and frequency increase the eddy currents generated, leading to greater energy losses. Additionally, thicker materials result in larger eddy currents, further amplifying the losses. The loss can be minimized by using laminated cores or materials with lower conductivity.

Why induced emf in transformers lag excitation current?
All magnetic materials require some energy before they will operate. You can think of it as the price of admission. In an electrical transformer, the excite current is actually a composite of the energy which is lost due to eddy currents in the magnetic material as well as hysteresis losses of the material. Excite current is both frequency and voltage dependent. Instead of saying, "before my husband will do anything I have to bake him a cake", you could say"before my transformer runs at 115Vinput, I have to supply x milliAmps of excite current just to get the core going." A special class of transformers known as CT's or Current Transformer's works in much the same way, except their voltage is reflected off the load instead of coming directly in through the primary. This energy is dissipated as heat. In power transformers, the concern is energy lost with no load connected on the output. In current transformers, the concern is the varying loss of accuracy due to the highly non-linear nature of excite current, especially at low excite levels.
Why is Huang he dangerous?
The Huang He, or Yellow River, is considered dangerous due to its frequent flooding, which has historically caused significant loss of life and property. The river carries a high sediment load, leading to siltation and changes in its course, which can exacerbate flooding in surrounding areas. Additionally, the river's unpredictable behavior, combined with human activities like dam construction and deforestation, increases the risk of disasters. These factors make managing the Huang He's waters a critical concern for the communities that depend on it.
Why european gold finch losing all his wings feather?
The European goldfinch may lose its wing feathers due to a variety of factors, including molting, which is a natural process where birds shed old feathers to make way for new growth. Additionally, external factors such as parasites, poor nutrition, or environmental stressors can affect feather health. In some cases, feather loss can be a sign of disease or injury. If the feather loss is excessive or unusual, it may indicate an underlying health issue that requires further investigation.
Who is Meg first to blame for the loss of Charles Wallace in A Wrinkle in Time?
In "A Wrinkle in Time," Meg Murry first blames herself for the loss of her younger brother, Charles Wallace. She feels responsible for his disappearance, believing that her own inadequacies and failures contributed to their current predicament. This self-blame reflects her insecurities and deep love for Charles, highlighting her emotional turmoil throughout the story.
Is there a lord loss movie?
no, there is no lord loss movie out at the moment
How eddy current losses andhysterious losses can be reduced?
eddy current can be reduced by using laminated cores. and also be reducing the thickness of the stampings. transformer iron loss is the combination of eddy current loss and hysterisis loss. both the losses depend on core of the transformer and iron loss is a constant loss.
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
A single-phase transformer when supplied from 220v50hz has eddy current loss of 50wif the transformer is connected to a voltage of 330v50hzthe eddy current loss will be?

What is AD current loss?
AD current loss could refer to a comic, called Eddy Current. It could also refer to AD loss, memory loss caused by Alzheimer's Disease.

What is eddy current loss in transformers?
Eddy current loss in Transformers is because of the eddy currents formed in the body of the magnetic core.Whenever a conductor(iron core) exposed to a changing magnetic field a magnetc field produced in the body of the magnetic core.That induce a circulating current in it.Which is called eddy current.In the case transformer it is loss.But it is useful in other purposes.
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
How do you minimize core losses?
Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
No load current of transformer is non sinusoidal even though sinusoidal voltage is provided in oc sc test?
eddy current loss in the transformer core is reduced by
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Why core loss depends on voltage?
Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.
