Step-by-step solution

AC generator-- Converts mechanical energy into electrical energy. A→IIA \to II.

Galvanometer-- Detects the presence of current in the circuit B−IB - I.

Transformer-- Changes an alternating voltage for smaller or greater value C−IVC - IV.

Metal detector-- Works on the principle of resonance in AC circuit D−IIID - III.
