1. FM radio stations use radio waves with frequencies from 88.0 to 108 MHz to broadcast their signals. Assuming that the inductance in Figure 24.4 has a value of 7.00 × 10-7 H, determine the range of capacitance values that are needed so the antenna can pick up all the radio waves broadcasted by FM stations.
2. An ac series circuit has an impedance of 114 Ω , and the phase angle between the current and the voltage of the generator is φ = -77 ˚. The circuit contains a resistor and either a capacitor or an inductor. Find (a) the resistance R and (b) the capacitive reactance XC or the inductive reactance XL, whichever is appropriate.
