A tank circuit, also called tuned circuit, resonant circuit, or LC circuit, is a circuit consisting of an inductor and a capacitor. The circuit can act as a resonator, storing energy oscillating at the circuit's resonant frequency.

Voltage output from a tank circuit
I have the following tank circuit. Now at resonance of about 50.054 MHz, the output voltage should be same as input, as the tank circuit would have a high resistance. … I have calculated the impedance of the tank circuit at the resonance frequency to be
\$Z_{total} = \dfrac{j\omega L}{1-{\omega}^2 LC}\$ = 4.5M\$\Omega\$
Then why is the output voltage so much attenuated …
