The value capacitor tunes the circuit to the radio station is 21.965 pf.
A capacitor is a device that stores electrical power in an electric-powered field by using a distinctive feature of amassing electric-powered charges on two near surfaces insulated from every different. it's far a passive electronic thing with two terminals. The impact of a capacitor is referred to as capacitance.
Capacitor, is a tool for storing electric electricity, including conductors in near proximity and insulated from every other. An easy instance of this kind of storage tool is the parallel-plate capacitor.
Calculation:-
For stunning natural frequency should be equal to frequency of radio wave
Wn = 1/√LC
given frequency f = 1550 kHz
inductance L = 480 μH
Wr = Wn
(2πf) = 1/√LC
(2πf)² = 1/LC
C = 1/(2πf)² × L
= 1/[2×π × 1550 × 10³]² × 480 × 10⁻⁶
= 52.77145 × 10⁻⁶/(1550)²
= 21.965 × 10⁻¹²
Value of cap[acitor C = 21.965 × 10⁻¹²
= 21.965 pf
