PhysicsMedium94×since 2002Q5923In series LCR circuit, the capacitance is changed from CCC to 4C4 C4C. To keep the resonance frequency unchanged, the new inductance should be:Aincreased by 2 L2 \mathrm{~L}2 LBreduced by 14 L\frac{1}{4} \mathrm{~L}41 LCreduced by 34 L\frac{3}{4} \mathrm{~L}43 LDincreased to 4 L4 \mathrm{~L}4 LCheck answerSkip
