(7 points) An ac voltmeter, which displays the rms voltage between the two points connected to its leads, is used to measure voltages in the circuit shown below. In this circuit, the ac generator has an rms voltage of \( 125 \mathrm{~V} \) and a frequency of \( 40 \mathrm{~Hz} \). The inductance in the circuit is \( 0.18 \mathrm{H} \), the capacitance is 68 \( \mu \mathrm{F} \), and the resistance is 70 \( \Omega \). (A) Calculate the impedance of this circuit. \( \quad \Omega \) (B) What is the resonant angular frequency of this circuit? \( \mathrm{rad} / \mathrm{s} \) (C) What is the rms current which flows in this circuit? (D) What is the voltmeter reading when it is connected to points A and B? (E) What is the voltmeter reading when it is connected to points B and C? (F) What is the voltmeter reading when it is connected to points \( \mathrm{C} \) and \( \mathrm{D} \) ? \( \mathrm{V} \) (G) What is the voltmeter reading when it is connected to points A and D? V
