resonant tank circuits

When a capacitor (C) and inductor (L) are connected in parallel, they form a resonant tank circuit that resonates at one frequency. The table below lists the theoretical resonant frequencies (in kilohertz) for some common values of capacitors (in picofarads) and inductors (in microhenrys). The real-world resonant frequencies will vary a little due to stray capacitances in the circuit components, variations in component values caused by temperature fluctuation, etc.
