Question

Question 3(iii)A transformer is used to change a high alternating e.m.f. to a low alternating e.m.f. of the same frequency.(a) Identify the type of transformer used for the above purpose.(b) State whether the turns ratio of the above transformer is = 1 or >1 or <1.

Accepted Answer

(a) Step down transformer(b) turns ratio is n < 1, i.e., number of turns in the secondary are less than the number of turns in the primary.
