A radio tune circuit consists of an inductor of inductance 0.4 H and
resistance 10 Ω connected in parallel with a variable capacitor of
capacitance set at 0.4 ?F. A radio signal captured by the receiver induces a
voltage of 0.01 V across the inductor. Calculate the frequency of the radio
waves. What is the effect of reducing the coil resistance to 5.0 Ω
