SATHEE: Electro Magnetic Induction And Alternating Currents Question 75

Electro Magnetic Induction And Alternating Currents Question 75

Question: For the series LCR circuit , what is the resonance frequency and the amplitude of the current at the resonating frequency [Kerala PET 2005]

Options:

A) $2500, r a d - s^{- 1}$ and $5 \sqrt{2}, A$

B) $2500, r a d - s^{- 1}$ and $5 A$

C) $2500, r a d - s^{- 1}$ and $\frac{5}{\sqrt{2}} A$

D) $25, r a d - s^{- 1}$ and $5 \sqrt{2}, A$

Show Answer

Answer:

Correct Answer: B

Solution:

Resonance frequency $ω = \frac{1}{\sqrt{L C}} = \frac{1}{\sqrt{8 \times 10^{- 3} \times 20 \times 10^{- 6}}} = 2500 r a d / \sec$ Resonance current = $\frac{V}{R} = \frac{220}{44} = 5 A$
