Match the List-I with List-II.

 

List I

 

List II

A

AC generator

I

Presence of both L and C

B

Transformer

II

Electromagnetic Induction

C

Resonance phenomenon to occur

III

Quality factor

D

Sharpness of resonance

IV

Mutual Inductance

Choose the correct answer from the options given below:

Options:

Answer:
C
Solution:

(A) An AC generator works on the electromagnetic induction principle. So,

(B) The transformer works on the principle of mutual induction. So,

(C) Resonance occurs when the value of inductive and capacitive reactance have equal magnitude but a phase difference of . So,

(D) The sharpness of resonance is defined using the quality factor which explains how fast energy decay in an oscillating system.
