Question

Complete the following diagram of a transformer and name the parts labelled A and B. Name the part you have drawn to complete the diagram. What is the material of this part? Is this transformer a step-up or step-down? Why?

Answer 1

In the given transformer diagram, A is the primary coil and B is the secondary coil. The missing part is the core, which is made of laminated soft iron to reduce eddy current losses. It is a step-down transformer because the number of turns in the primary coil is greater than that in the secondary coil, resulting in a lower output voltage than the input voltage.
