The AM band extends from approximately 500 kHz to 1,600 kHz. If a 1.9-H inductor is...
An electronics hobbyist is building a radio set to receive the AM band, with frequencies from 520 kHz to 1700 kHz. The antenna, which also serves as the inductor in an LC circuit, has an inductance of 206 . She needs to add a variable capacitor whose capacitance she can adjust to tune the radio. Part A What is the minimum capacitance the capacitor must have? Part B What is the maximum capacitance the capacitor must have?
An electronics hobbyist is building a radio set to receive the AM band, with frequencies from 520 kHz to 1700 kHz. The antenna, which also serves as the inductor in an LC circuit, has an inductance of 230 H. She needs to add a variable capacitor whose capacitance she can adjust to tune the radio. Review Part A What is the minimum capacitance the capacitor must have? Express your answer with the appropriate units. 0 FL HA ? Cmin =...
A 1200 Ω resistor, a 600 nF capacitor and a 25 μH inductor are placed in series with a variable frequency AC source. 1. Find the reactances χC and χL and the circuit impedance Z when ƒ = 1500 Hz. 2. The fixed capacitor is replaced with a variable capacitor, and we are going to use the circuit to tune an AM radio, searching for the resonant frequencies. Since the AM band holds frequencies between 520 kHz and 1610 kHz,...
An electronics hobbyist is building a radio set to receive the AM band, with frequencies from520 kHz to 1500 kHz . The antenna, which also serves as the inductor in an LC circuit, has an inductance of 274 μH . She needs to add a variable capacitor whose capacitance she can adjust to tune the radio. What is the minimum capacitance the capacitor must have? Cmin = ?
