Transformer diagram class 12

Hint – You can start by defining what a transformer is. Then move on to describe the principle behind the transformer. Then describe the basic setup of a transformer. Then finally write how a transformer works. An electrical device that can change the A.C. current is known as a transformer. Principle – A transformer works on the principle of mutual induction. Mutual induction is the phenomenon by which when the amount of magnetic flux linked with a coil changes, an E.M.F. is induced in the neighboring coil. Construction – A transformer is made up of a rectangular iron core. Two coils, a primary $($. Both these coils are insulated from the Ferro-magnetic iron core. The source of the alternate current is connected to the primary winding and the output is obtained through the secondary winding which is connected in parallel to a resistance $R$. Working - For an ideal transformer, we consider that resistances of the primary and secondary coils are negligible. Let the $E.M.F.$ of the alternate current supplied by the A.C source be $$). Additionally an iron core is used because it is a ferromagnetic material which helps in increasing the strength of the magnetic field.

transformer circuit diagram class 12 is an important part of learning the fundamentals of electrical engineering and is an integral tool for students pursuing a degree in this field. It plays an important role in the overall design and construction of electrical systems, ranging from the simplest of circuits to the most complex. When it comes to understanding transformer circuit diagrams, the key is to have a strong foundation in the knowledge of electrical components. Knowing which components are involved in each circuit and what their functional roles are is vital for accurate circuit analysis. This information can be obtained from textbooks or tutorials available on the internet. Class 12 studies typically involve major portions of the transformer circuit diagram including the primary and secondary windings, various parameters, the AC source, and step-by-step calculations. The first step of analyzing a transformer circuit is to identify all the elementary components in the circuit, such as resistors, capacitors, transformers, and inductors, based on the symbols used in the transformer circuit diagram. Once the different components are identified, the next step is to calculate the equivalent resistance and reactance between the two windings, taking into account the various parameters, such as input voltage, output voltage, and leakage inductance. After these calculations are completed, a voltage divider can be used to check if the equivalent resistance between the primar...

Transformer—Transformer is a device which converts low alternating voltage at high alternating current into high alternating voltage at low alternating current and vice versa. It does not work on D.C. Principle—It works on the principle of “mutual induction”. It states that if magnetic changes in primary coil then EMF is induced in secondary coil and vice versa. Construction Working In a transformer these are two types of coil : Primary and Secondary. Primary coil is attached with input whereas secondary coil is connected to output. Through induction alternating voltage may be increased or decreased. It works on the “Coupling Method”. Theory According to law of Faraday Flux changes in the coil is directly proportional to the no. of turns in the coil eq n is called working theory of a Transformer upto here only N s/N pis called Transformation Ratio It is represented by k K = N s/N p…(vi) If K > 1, then transformer is step-up Transformer. If k N p Step-Down Transformer—Transformer is said to be step-down transformer if it converts high alternating voltage at low alternating current into low alternating voltage at high alternating current. Number of turns in a primary coil is larger than no. of turns in a secondary coil. i.e. N s> N p Uses of Transformer (i) A step-down transformer is used for the purpose of obtaining large electric current for electrical welding.

Hint: In the given diagram, one end is at higher potential difference while the other end is at lower difference. The given diagram is of a transformer. A transformer is a device which is capable of transferring electric current from one circuit to another circuit. Complete answer: As the given diagram is of transformer, we will complete the diagram accordingly. In a transformer, the coil is of iron. The core is made up of thin laminated sheets of iron.The complete and labelled diagram is given below: There are two types of winding in the transformer. The winding on the left side (input side) is known as primary winding. The winding on the right side is the output side. The winding on the output side is known as secondary winding. Based on the number of turns there are two types of transformers. 1) Step up transformer 2) Step down transformer 1) Step-up transformer: When the voltage at output is more than the input voltage, it is known as a step-up transformer. In step-up transformers, the number of turns in secondary winding is more than in primary winding. 2) Step-down transformer: When the voltage at output is less than the input voltage, it is known as a step-down transformer. In step-down transformers, the number of turns in secondary winding is less than number of turns in primary winding. Note: When the output voltage is less than input voltage, the given transformer is a step-down transformer. Number of turns is important in transformers. In some transformers, the ...
