🔍 Key Concepts

• Formula for resonant frequency of an LC circuit (ignore resistance for basic resonance calculation) • Unit conversions: picofarads to farads, microhenrys to henrys • Effect of resistance on resonant frequency vs. on bandwidth and sharpness of tuning

💭 Think About

• Write down the standard formula for the resonant frequency of a series LC circuit and solve it symbolically before plugging in numbers • Convert the capacitor and inductor values into base SI units and carefully check the powers of ten when doing your calculation • After you get a numerical answer in hertz, convert it to kilohertz and compare with the options

✅ Before You Answer

• Be sure you are using inductance in henrys (H) and capacitance in farads (F) before calculating • Confirm whether the 10 ohms resistance actually changes the resonant frequency in the ideal LC resonance formula • Double-check your powers of ten when converting pF and µH to F and H so your answer is in the correct kHz range
