Answer & Solution
Correct Answer
(A) \((A)-(II), B-(I), (C)-(IV), (D)-(III)\)
Step-by-step Solution
Detailed explanation
\(AC\) generator converts mechanical energy into electrical energy. Galvanometer shows deflection when current passes through it so it is used to show presence of current in any wire.
Transformer is used to step up or step down the voltage. Metals detectors contain inductor coils and use principle of induction and resonance in \(AC\) circuit.
