Question 11

The diagram in figure shows the core of a transformer and it's input and output connections.

The diagram in figure shows the core of a transformer and it's input and output connections. State the material used for the core and describe it's structure. Complete the diagram of the transformer and connections by labelling all parts joined by you. Name the transformer step up or step down. Electromagnetism, Concise Physics Solutions ICSE Class 10.

(a) State the material used for the core and describe it's structure.

(b) Complete the diagram of the transformer and connections by labelling all parts joined by you.

(c) Name the transformer : step up or step down.

Answer

(a) The material used for the core is soft iron. It is made up from thin laminated sheets of soft iron of T and U shape, placed alternately one above the other and insulated from each other by paint (or varnish) coating over them.

(b) Completed diagram is shown below:
