No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.

How do you improve the flux linkage between the primary and secondary windings in a transformer?
by using an iron core
What is transformer ratios?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
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.
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.
What is iron loss?
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 is the core laminated?
The iron core of Transformers is laminated to reduce eddy currents, which cause a loss of energy.
How many types of losses in transformer?
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
Why is the magnetic core laminaled?
The iron core of transformers is laminated to reduce eddy currents, which cause a loss of energy.
What is mean by magnetizing current of transformer?
A: As current flow in the primary it will magnetize the core of the iron in the transformer that is called magnetizing.
What makes soft iron a suitable core for transformers?
Low hysterisis loss and high permeability
What is hysteresis loss in transformers?
Hysterisis losses are the losses which are taking place in the iron or steel core due to reversal of magnetisation of steel core.
What metal found in the inner core?
The primary metals in the core are iron and nickel with lesser amounts of other heavy metals.
What is the sphere of solid material at the center of Earth?
It is composed of an iron and nickel alloy, and is called the inner core.
What do we think is the primary source of the earth's magnetic field?
The Earth's Iron Core
Why you use only iron core in transformers?
iron has high permeabiliy than others and also less leakageAnswerGenerally speaking, transformer cores are manufactured from laminated sheets of silicon steel, not iron.
Can you able to use plastic instead of iron core in transformers?
It is because if we use a plastic as a core of the transformer then induced emf can to be produced also generated heat will damage the plastic .
How many metals found in the inner core?
The primary metals in the core are iron and nickel with lesser amounts of other heavy metals.
