Question

Draw a schematic arrangement for winding of primary and secondary coils 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

number of secondary and primary windings andprimary 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 actual transformers. [

Answer 1

State the inderlying principle of a transformer and and obtain the expression of the ratio of the of secondary and prymary voltages in terms of the number of secondary and primary windings and the nimber of and primary and secondary
