1. Consider a radio receiver that is configured with a loop antenna, a variable capacitor and a pickup coil. By adjusting he value of the capacitance, it is possible to adjust the corresponding resonant frequency of the circuit and receive several radio stations. If the inductance of the coil is 2 mH, and we want to hear a radio station at 99.9 MHz, what is the capacitance of the circuit? (2 points).
A radio can be tuned into a particular station frequency by adjusting the capacitance in an L-C circuit. Suppose that the minimum capacitance of a variable capacitor in a radio is 4.14 pF . What is the inductance L of a coil connected to this capacitor if the oscillation frequency of the L-C circuit is 1.60 MHz , corresponding to one end of the AM radio broadcast band, when the capacitor is set to its minimum capacitance?

A tank circuit in a radio transmitter is a series RCL circuit connected to an antenna. The antenna broadcasts radio signals at the resonant frequency of the tank circuit. Suppose that a certain tank circuit in a shortwave radio transmitter has a fixed capacitance of 1.2 x 10-11 F and a variable inductance. If the antenna is intended to broadcast radio signals ranging in frequency from 4.6 MHz to 8.4 MHz, find the (a) minimum and (b) maximum inductance of...
3) In a radio receiver the antenna consists of a coil (see lecture notes). The signal Vin(t)-Voeis filtered by the combination of the coil inductance L, the coil resistance R and a capacitor C (see Fig. below). Equating input (signal) voltage to the sum of the voltages across the inductance, resistance and capacitance find, the voltage azross the capacitor Vc(t). Show that it is maximal when o-00-1/LC. Thus by changing the capacitor one can tune in to a given emission...
