Answer: C. 1.58
Q-factor of RLC series circuit given is 1.58.
Solution:
Q-factor of RLC series circuit = ω0L/R
Here ω0 is the resonance frequency
ω0=1/√LC=1/√[(25×10-3)(100×10-6)]=632.45
⟹ Q- factor=ω0L/R
⟹Q=632.45×(25×10-3)/10=1.58
Q-factor of RLC series circuit given is 1.58.
Hence option C is the correct answer.
