Iron losses (Pi) are independent of of load which occur due to pulsation of flux in the core.
Iron losses include both Hysteresis loss and eddy current loss and is same at all the loads.

Why iron loss is constant but copper loss is variable in a transformer?
Iron loss it includes the core loss is partically the same at all loads and copper loss the value of cu loss is found from short circuit test
Why the iron losses in a transformer is constant at all load prove that?
since the iron loss depends only on the volage and frequency,the supply volage is 230v ac.Hence iron loss is always constant
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
How does Lenz's Law explain power loss in transformers?
It doesn't, really. The power loss in transformers is broken down into copper loss and iron loss. The copper loss comes from the resistance of the windings in the transformer and depends on the load current, while the iron loss in the magnetic core depends on the magnetic flux density and is constant if the supply voltage is constant.
How Core Loss is dependent on Frequency?
since at no load only excitation current(responsible for core loss ie iron loss) flow on the primary side so core loss current will be 1A and core loss = v1*i1*powerfactor. core loss = 1*11000*0.24= 2640watt.
What are core losses?
Iron losses are termed as core losses. There are mainly two losses - Copper loss and iron loss. Iron loss is no load loss.
Difference between iron loss and hystersis loss?
In a transformer, there are two basic types of losses that are broken down even further: iron loss and copper loss. Hysteresis loss is part of what makes up the iron loss, but is not the only part of iron losses.
Why iron loss cald constant power loss?
How to calculate iron losses in dc machine
Why iron loss is constant but copper loss is variable in a transformer?
Iron loss it includes the core loss is partically the same at all loads and copper loss the value of cu loss is found from short circuit test
Why do women need iron?
They suffer iron loss when they menstruate.
What is the losses of three phase induction motors?
Iron Loss Copper Loss Frictional loss
What creates the loss of iron in anemia?
There are several things that can cause the human body to lose iron. Blood loss, a lack of iron in your diet, and an inability to absorb iron are all causes to losing iron. Pregnancy can also cause your body to lose iron.
Why the iron losses in a transformer is constant at all load prove that?
since the iron loss depends only on the volage and frequency,the supply volage is 230v ac.Hence iron loss is always constant
Does a low amount of iron in the body cause low energy and a loss of appetite?
i think the loss of apetite is the reson that you have a low amount of iron in your body not the othert way around Iron defitiency causes loss of energy, becoming very distracted in class, alotof spacing out ,anemia ,and sungy nails . i think the loss of apetite is the reson that you have a low amount of iron in your body not the othert way around Iron defitiency causes loss of energy, becoming very distracted in class, alotof spacing out ,anemia ,and sungy nails .
Why the efficiency of a power transformer increases with a decrease in Load at constant PF?
Maximum efficiency of a power transformer occurs when copper loss equals to iron losses. Decrease in current does not result in increase in efficiency unless the copper loss was more than iron loss and the decreased current made the copper loss is reduced and became equal to iron loss at some point.
Flat iron cause hair loss?
yes
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
