This is to certify that______, student of Class XII, Kendriya Vidyalaya, Laitkor Peak, Shillong has completed the project titled Transformer for the Physics practical evaluation of CBSE , and submitted satisfactory report, as compiled in the.

Jain Principal M. Public School, Udaipur Raj. Introduction The transformer is a device used for converting a low alternating voltage to a high alternating voltage or a high alternating voltage into a low alternating voltage.

Principal It is based on the principle of mutual induction that is if a varying current is set-up in a circuit induced e. Step Down Transformer In our project step-down transformer is used: Construction The transformer consists of two coils.

Then, the induced e. The efficiency of the transformer is given by: If Ip and Is be the currents in the primary and secondary circuits. Energy Losses in Transformer In practice, the output energy of a transformer is always less than the input energy, because energy losses occur due to a number of reasons as explained below.

Loss of Magnetic Flux: The coupling between the coils is seldom perfect.

Iron Loss: In actual iron cores inspite of lamination, Eddy currents are produced. The magnitude of eddy current may, however be small.

And a part of energy is lost as the heat produced in the iron core. Copper Loss: In practice, the coils of the transformer possess resistance. Hysteresis Loss: The alternating current in the coil tapes the iron core through complete cycle of magnetization.

So Energy is lost due to hysteresis.

Magneto restriction: The alternating current in the Transformer may be set its parts in to vibrations and sound may be produced. It is called humming. Thus, a part of energy may be lost due to humming. Bibliography www. Mahesh Sahu.

Step Down Transformer In our project step-down transformer is used: This transformer converts high voltage at alternating current into low voltage alternating current.So, whole of the magnetic flux produced by the primary coil is not linked up with the secondary coil.

Such instruments are called magnetic flow meters. Contents 1.

For example, chemistry studies properties, structures, and reactions of matter chemistry's focus on the molecular and atomic scale distinguishes it from physics. Nabhdeep Chaudhary.

Let be the rate of change of flux in each turn of the primary coil. Later, quantum field theory unified quantum mechanics and special relativity.
