Out of two arrangements of primary and secondary windings in a transfomers, which will have higher efficiency and why ?

Draw a schematic arrangement for winding of primary and secondary coil in a transformer when the two coils are found on top of each other.

Draw a schematic arrangement for winding of primary and secondary coil in a transformer when the two coils are wound on top of each other. (ii) State the underlying principle of a transformer and obtain the expression for the ratio of secondary to primary voltage in terms of the (a) number of secondary and primary windings and (b) primary and secondary currents. (iii) Write the main assumption involved in deriving the above relations. (iv) Write any two reasons due to which energy losses may occur in actul transformers.

Show diagramatically two different arrangements used for winding the primary and secondary coils in a transformer. Assuming the transformer to be an ideal one write expressions fo rthe ratio of its output current to input current in terms of the number of turns in the primary and secondary coils. Mention two reasons for energy losses in an actual transformer.

The primary of a transformer when connected to a dc battery of 10 volt draws a current of 1 mA. The number of turns of the primary and secondary windings are 50 and 100 respectively.The voltage in the secondary and the current drawn by the circuit in the secondary are respectively
