defence exam Army Havildar SAC Mock Test Series 2025 Physics Electromagnetic Induction and Inductance Inductors and Inductance
In series LCR circuit, the capacitance is changed from C to 4C. To keep the resonance frequency unchanged, the new inductance should be :
1
reduced by \(\frac{1}{4}\)L
2
increased by 2L
3
reduced by \(\frac{3}{4}\)L
4
increased to 4L
