Question

Draw labelled diagram to show various components of a

(1) Step up transformer

(2) Step down transformer.

Answer 1

1. STEP-UP TRANSFORMER : A transformer which increases the applied e.m.f. of an alternating current is called SET-UP TRANSFORMER. Number of turns in SECONDARY Coil Should be MORE.

2. STEP-DOWN TRANSFORMER : “A transformer which DECREASES the applied e.m.f. of alternating current is called STEP-DOWN TRANSFORMER.”
