Match the List-I with List-II.

 List I List II
AAC generatorIPresence of both L and C
BTransformerIIElectromagnetic Induction
CResonance phenomenon to occurIIIQuality factor
DSharpness of resonanceIVMutual 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, AII

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

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

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