What is a tuned circuit?

What phenomenon can be observed in a tuned circuit?

What are the essential components in a tuning circuit?

The tuned collector oscillator circuit used in the local oscillator of a ratio receiver makes use of a tuned circuit with L = 60 mu H and C = 400 pE . Calculate the frequency of oscillations.

In a simple AM transmitter, the tuned circuit uses a coil of 40muH and a shunt capacitor of 1 n F. If the oscillator output is modulated by audio frequencies upto 5kHz, what is the frequency range occupied by side bands?

The condenser used in the tuning circuit of radio receiver is.

The frequency of a tuning fork is 120 Hz. What is its time period?

A radio can tune over the frequency range of a portion of MW broadcast band: (800 kHz to 1200 kHz). If its LC circuit has an effective inductance of 200muH , what must be the range of its variable capacitor? (Hint: For tuning, the natural frequency i.e., the frequency of free oscillations of the LC circuit should be equal to the frequency of the radio wave.]

A coil of inductance 0.4 mH is connected to a capacitor of capacitance 400 pF. To what wavelength is this circuit tuned ?
