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:

Answer:

Solution:

(A) An AC generator works on the electromagnetic induction principle. So, $(A) \to I I$

(B) The transformer works on the principle of mutual induction. So, $(B) \to I V$

(C) Resonance occurs when the value of inductive and capacitive reactance have equal magnitude but a phase difference of $180 °$ . So, $(C) \to I$

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