MHT CET 2024 Physics question
LC series resonant circuit produces resonant frequency 'f'. if 'L' is tripled and 'C' is increased by 3C, the resonant frequency will be
Answer: (B)
Solution
The resonant frequency is . The inductance becomes . Capacitance "increased by " becomes . Then \dfrac{1}{2π\sqrt{3L· 4C}}$ =
