A tank circuit in a radio transmitter is a series RCL circuit connected to an antenna. The antenna broadcastsradio 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 1.8 x10-11 F and a variable inductance. If the antennais intended to broadcast radio signals ranging in frequency from4.3 MHz to 9.7 MHz, find the (a) minimumand (b) maximum inductance of the tank circuit.
