A resonant circuit consists of a 4 nF capacitor in parallel with a 100 (mu)H coil that has a coil resistance of 5 (Omega). Determine the resonant frequency and bandwidth. Further, assume that this circuit is now loaded by an amplifier that has an input impedance equivalent to 10 k(Omega) resistive in parallel with 500 pF of input capacitance.
Inductor and Capacitor Basics | Energy Storage Devices
When calculating equivalent capacitance, capacitors in series combine like resistors in parallel and capacitors in parallel combine like resistors in series. Discrete Capacitors Actual capacitors are rarely constructed of two parallel plates separated by air because this configuration either yields very low values of capacitance or requires very large plate areas.
