JEE Main level, single correct, medium

178 of 190

Question 178 of 190

Match List - I with List - II. List-I List-II (A) AC generator (I) Detects the presence of current in the circuit (B) Galvanometer (II) Converts mechanical energy into electrical energy (C) Transformer (III) Works on the principle of resonance in AC circuit (D) Metal detector (IV) Changes an alternating voltage for smaller or greater value

Show answer and solution

Answer: (A) (A)−(II),(B)−(I),(C)−(IV),(D)−(III)\left(A\right)-\left(II\right),\left(B\right)-\left(I\right),\left(C\right)-\left(IV\right),\left(D\right)-\left(III\right)

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