I have to design a single phase/50Hz step down transformer. Following information is given

Primary Voltage =240V, Secondary Voltage and current on secondary side should be 24V and 2A respectively.

efficiency should be in range of 70 to 80%.

Provide me all the necessary calculations to design this step down transformer.

And also note down all the hardware components that i should buy for this design.

Note: Tell me if i have missed any information for this project.
